|
1. Introduction *print-intro*
|
|
|
|
On MS-Windows Vim can print your text on any installed printer. On other
|
|
systems a PostScript file is produced. This can be directly sent to a
|
|
PostScript printer. For other printers a program like ghostscript needs to be
|
|
used.
|
|
|
|
Note: If you have problems printing with |:hardcopy|, an alternative is to use
|
|
|:TOhtml| and print the resulting html file from a browser.
|
|
|
|
*:ha* *:hardcopy* *E237* *E238* *E324*
|
|
:[range]ha[rdcopy][!] [arguments]
|
|
Send [range] lines (default whole file) to the
|
|
printer.
|
|
|
|
On MS-Windows a dialog is displayed to allow selection
|
|
of printer, paper size etc. To skip the dialog, use
|
|
the [!]. In this case the printer defined by
|
|
'printdevice' is used, or, if 'printdevice' is empty,
|
|
the system default printer.
|
|
|
|
For systems other than MS-Windows, PostScript is
|
|
written in a temp file and 'printexpr' is used to
|
|
actually print it. Then [arguments] can be used by
|
|
'printexpr' through |v:cmdarg|. Otherwise [arguments]
|
|
is ignored. 'printoptions' can be used to specify
|
|
paper size, duplex, etc.
|
|
Note: If you want PDF, there are tools such as
|
|
"ps2pdf" that can convert the PostScript to PDF.
|
|
|
|
:[range]ha[rdcopy][!] >{filename}
|
|
As above, but write the resulting PostScript in file
|
|
{filename}.
|
|
Things like "%" are expanded |cmdline-special|
|
|
Careful: An existing file is silently overwritten.
|
|
On MS-Windows use the "print to file" feature of the
|
|
printer driver.
|
|
|
|
Progress is displayed during printing as a page number and a percentage. To
|
|
abort printing use the interrupt key (CTRL-C or, on MS-systems, CTRL-Break).
|
|
|
|
Printer output is controlled by the 'printfont' and 'printoptions' options.
|
|
'printheader' specifies the format of a page header.
|
|
|
|
The printed file is always limited to the selected margins, irrespective of
|
|
the current window's 'wrap' or 'linebreak' settings. The "wrap" item in
|
|
'printoptions' can be used to switch wrapping off.
|
|
The current highlighting colors are used in the printout, with the following
|
|
considerations:
|
|
1) The normal background is always rendered as white (i.e. blank paper).
|
|
2) White text or the default foreground is rendered as black, so that it shows
|
|
up!
|
|
3) If 'background' is "dark", then the colours are darkened to compensate for
|
|
the fact that otherwise they would be too bright to show up clearly on
|
|
white paper.
|
|
|
|
==============================================================================
|
|
2. Print options *print-options*
|
|
|
|
Here are the details for the options that change the way printing is done.
|
|
For generic info about setting options see |options.txt|.
|
|
|
|
*pdev-option*
|
|
'printdevice' 'pdev' string (default empty)
|
|
global
|
|
This defines the name of the printer to be used when the |:hardcopy| command
|
|
is issued with a bang (!) to skip the printer selection dialog. On Win32, it
|
|
should be the printer name exactly as it appears in the standard printer
|
|
dialog.
|
|
If the option is empty, then vim will use the system default printer for
|
|
":hardcopy!"
|
|
|
|
*penc-option* *E620*
|
|
'printencoding' 'penc' String (default empty, except for:
|
|
Windows: cp1252,
|
|
Macintosh: mac-roman,
|
|
HPUX: hp-roman8)
|
|
global
|
|
Sets the character encoding used when printing. This option tells Vim which
|
|
print character encoding file from the "print" directory in 'runtimepath' to
|
|
use.
|
|
|
|
This option will accept any value from |encoding-names|. Any recognized names
|
|
are converted to Vim standard names - see 'encoding' for more details. Names
|
|
not recognized by Vim will just be converted to lower case and underscores
|
|
replaced with '-' signs.
|
|
|
|
If 'printencoding' is empty or Vim cannot find the file then it will use
|
|
'encoding' (if it is set an 8-bit encoding) to find the print character
|
|
encoding file. If Vim is unable to find a character encoding file then it
|
|
will use the "latin1" print character encoding file.
|
|
|
|
When 'encoding' is set to a multibyte encoding, Vim will try to convert
|
|
characters to the printing encoding for printing (if 'printencoding' is empty
|
|
then the conversion will be to latin1). If no conversion is possible then
|
|
printing will fail. Any characters that cannot be converted will be replaced
|
|
with upside down question marks.
|
|
|
|
Two print character encoding files are provided to support default Mac and
|
|
HPUX character encodings and are used by default on these platforms. Code page
|
|
1252 print character encoding is used by default on the Windows platform.
|
|
|
|
*pexpr-option*
|
|
'printexpr' 'pexpr' String (default: see below)
|
|
global
|
|
Expression that is evaluated to print the PostScript produced with
|
|
|:hardcopy|.
|
|
The file name to be printed is in |v:fname_in|.
|
|
The arguments to the ":hardcopy" command are in |v:cmdarg|.
|
|
The expression must take care of deleting the file after printing it.
|
|
When there is an error, the expression must return a non-zero number.
|
|
If there is no error, return zero or an empty string.
|
|
The default for non MS-Windows systems is to simply use "lpr" to print the
|
|
file: >
|
|
|
|
system(['lpr']
|
|
+ (empty(&printdevice)?[]:['-P', &printdevice])
|
|
+ [v:fname_in])
|
|
. delete(v:fname_in)
|
|
+ v:shell_error
|
|
|
|
On MS-Dos and MS-Windows machines the default is to copy the file to the
|
|
currently specified printdevice: >
|
|
|
|
system(['copy', v:fname_in, empty(&printdevice)?'LPT1':&printdevice])
|
|
. delete(v:fname_in)
|
|
|
|
If you change this option, using a function is an easy way to avoid having to
|
|
escape all the spaces. Example: >
|
|
|
|
:set printexpr=PrintFile(v:fname_in)
|
|
:function PrintFile(fname)
|
|
: call system("ghostview " . a:fname)
|
|
: call delete(a:fname)
|
|
: return v:shell_error
|
|
:endfunc
|
|
|
|
Be aware that some print programs return control before they have read the
|
|
file. If you delete the file too soon it will not be printed. These programs
|
|
usually offer an option to have them remove the file when printing is done.
|
|
*E365*
|
|
If evaluating the expression fails or it results in a non-zero number, you get
|
|
an error message. In that case Vim will delete the file. In the default
|
|
value for non-MS-Windows a trick is used: Adding "v:shell_error" will result
|
|
in a non-zero number when the system() call fails.
|
|
|
|
This option cannot be set from a |modeline| or in the |sandbox|, for security
|
|
reasons.
|
|
|
|
*pfn-option* *E613*
|
|
'printfont' 'pfn' string (default "courier")
|
|
global
|
|
This is the name of the font that will be used for the |:hardcopy| command's
|
|
output. It has the same format as the 'guifont' option, except that only one
|
|
font may be named, and the special "guifont=*" syntax is not available.
|
|
|
|
In the Win32 GUI version this specifies a font name with its extra attributes,
|
|
as with the 'guifont' option.
|
|
|
|
For other systems, only ":h11" is recognized, where "11" is the point size of
|
|
the font. When omitted, the point size is 10.
|
|
|
|
*pheader-option*
|
|
'printheader' 'pheader' string (default "%<%f%h%m%=Page %N")
|
|
global
|
|
This defines the format of the header produced in |:hardcopy| output. The
|
|
option is defined in the same way as the 'statusline' option. The same simple
|
|
header is used when this option is empty.
|
|
|
|
*pmbcs-option*
|
|
'printmbcharset' 'pmbcs' string (default "")
|
|
global
|
|
Sets the CJK character set to be used when generating CJK output from
|
|
|:hardcopy|. The following predefined values are currently recognised by Vim:
|
|
|
|

To set up the correct encoding and character set for printing some
|
|
Japanese text you would do the following; >
|
|
:set printencoding=euc-jp
|
|
:set printmbcharset=JIS_X_1983
|
|
|
|
If 'printmbcharset' is not one of the above values then it is assumed to
|
|
specify a custom multibyte character set and no check will be made that it is
|
|
compatible with the value for 'printencoding'. Vim will look for a file
|
|
defining the character set in the "print" directory in 'runtimepath'.
|
|
|
|
*pmbfn-option*
|
|
'printmbfont' 'pmbfn' string (default "")
|
|
global
|
|
This is a comma-separated list of fields for font names to be used when
|
|
generating CJK output from |:hardcopy|. Each font name has to be preceded
|
|
with a letter indicating the style the font is to be used for as follows:
|
|
|
|
r:{font-name} font to use for normal characters
|
|
b:{font-name} font to use for bold characters
|
|
i:{font-name} font to use for italic characters
|
|
o:{font-name} font to use for bold-italic characters
|
|
|
|
A field with the r: prefix must be specified when doing CJK printing. The
|
|
other fontname specifiers are optional. If a specifier is missing then
|
|
another font will be used as follows:
|
|
|
|
if b: is missing, then use r:
|
|
if i: is missing, then use r:
|
|
if o: is missing, then use b:
|
|
|
|
Some CJK fonts do not contain characters for codes in the ASCII code range.
|
|
Also, some characters in the CJK ASCII code ranges differ in a few code points
|
|
from traditional ASCII characters. There are two additional fields to control
|
|
printing of characters in the ASCII code range.
|
|
|
|
c:yes Use Courier font for characters in the ASCII
|
|
c:no (default) code range.
|
|
|
|
a:yes Use ASCII character set for codes in the ASCII
|
|
a:no (default) code range.
|
|
|
|
The following is an example of specifying two multibyte fonts, one for normal
|
|
and italic printing and one for bold and bold-italic printing, and using
|
|
Courier to print codes in the ASCII code range but using the national
|
|
character set: >
|
|
:set printmbfont=r:WadaMin-Regular,b:WadaMin-Bold,c:yes
|
|
<
|
|
*popt-option*
|
|
'printoptions' 'popt' string (default "")
|
|
global
|
|
This is a comma-separated list of items that control the format of the output
|
|
of |:hardcopy|:
|
|
|
|
left:{spec} left margin (default: 10pc)
|
|
right:{spec} right margin (default: 5pc)
|
|
top:{spec} top margin (default: 5pc)
|
|
bottom:{spec} bottom margin (default: 5pc)
|
|
{spec} is a number followed by "in" for inches, "pt"
|
|
for points (1 point is 1/72 of an inch), "mm" for
|
|
millimeters or "pc" for a percentage of the media
|
|
size.
|
|
Weird example:
|
|
left:2in,top:30pt,right:16mm,bottom:3pc
|
|
If the unit is not recognized there is no error and
|
|
the default value is used.
|
|
|
|
header:{nr} Number of lines to reserve for the header.
|
|
Only the first line is actually filled, thus when {nr}
|
|
is 2 there is one empty line. The header is formatted
|
|
according to 'printheader'.
|
|
header:0 Do not print a header.
|
|
header:2 (default) Use two lines for the header
|
|
|
|
syntax:n Do not use syntax highlighting. This is faster and
|
|
thus useful when printing large files.
|
|
syntax:y Do syntax highlighting.
|
|
syntax:a (default) Use syntax highlighting if the printer appears to be
|
|
able to print color or grey.
|
|
|
|
number:y Include line numbers in the printed output.
|
|
number:n (default) No line numbers.
|
|
|
|
wrap:y (default) Wrap long lines.
|
|
wrap:n Truncate long lines.
|
|
|
|
duplex:off Print on one side.
|
|
duplex:long (default) Print on both sides (when possible), bind on long
|
|
side.
|
|
duplex:short Print on both sides (when possible), bind on short
|
|
side.
|
|
|
|
collate:y (default) Collating: 1 2 3, 1 2 3, 1 2 3
|
|
collate:n No collating: 1 1 1, 2 2 2, 3 3 3
|
|
|
|
jobsplit:n (default) Do all copies in one print job
|
|
jobsplit:y Do each copy as a separate print job. Useful when
|
|
doing N-up postprocessing.
|
|
|
|
portrait:y (default) Orientation is portrait.
|
|
portrait:n Orientation is landscape.
|
|
*a4* *letter*
|
|
paper:A4 (default) Paper size: A4
|
|
paper:{name} Paper size from this table:

3. PostScript Printing *postscript-printing*
|
|
*E455* *E456* *E457* *E624*
|
|
Provided you have enough disk space there should be no problems generating a
|
|
PostScript file. You need to have the runtime files correctly installed (if
|
|
you can find the help files, they probably are).
|
|
|
|
There are currently a number of limitations with PostScript printing:
|
|
|
|
- 'printfont' - The font name is ignored (the Courier family is always used -
|
|
it should be available on all PostScript printers) but the font size is
|
|
used.
|
|
|
|
- 'printoptions' - The duplex setting is used when generating PostScript
|
|
output, but it is up to the printer to take notice of the setting. If the
|
|
printer does not support duplex printing then it should be silently ignored.
|
|
Some printers, however, don't print at all.
|
|
|
|
- 8-bit support - While a number of 8-bit print character encodings are
|
|
supported it is possible that some characters will not print. Whether a
|
|
character will print depends on the font in the printer knowing the
|
|
character. Missing characters will be replaced with an upside down question
|
|
mark, or a space if that character is also not known by the font. It may be
|
|
possible to get all the characters in an encoding to print by installing a
|
|
new version of the Courier font family.
|
|
|
|
- Multi-byte support - Currently Vim will try to convert multibyte characters
|
|
to the 8-bit encoding specified by 'printencoding' (or latin1 if it is
|
|
empty). Any characters that are not successfully converted are shown as
|
|
unknown characters. Printing will fail if Vim cannot convert the multibyte
|
|
to the 8-bit encoding.
|
|
|
|
==============================================================================
|
|
4. Custom 8-bit Print Character Encodings *postscript-print-encoding*
|
|
*E618* *E619*
|
|
To use your own print character encoding when printing 8-bit character data
|
|
you need to define your own PostScript font encoding vector. Details on how
|
|
to define a font encoding vector is beyond the scope of this help file, but
|
|
you can find details in the PostScript Language Reference Manual, 3rd Edition,
|
|
published by Addison-Wesley and available in PDF form at
|
|
http://www.adobe.com/. The following describes what you need to do for Vim to
|
|
locate and use your print character encoding.
|
|
|
|
i. Decide on a unique name for your encoding vector, one that does not clash
|
|
with any of the recognized or standard encoding names that Vim uses (see
|
|
|encoding-names| for a list), and that no one else is likely to use.
|
|
ii. Copy $VIMRUNTIME/print/latin1.ps to the print subdirectory in your
|
|
'runtimepath' and rename it with your unique name.
|
|
iii. Edit your renamed copy of latin1.ps, replacing all occurrences of latin1
|
|
with your unique name (don't forget the line starting %%Title:), and
|
|
modify the array of glyph names to define your new encoding vector. The
|
|
array must have exactly 256 entries or you will not be able to print!
|
|
iv. Within Vim, set 'printencoding' to your unique encoding name and then
|
|
print your file. Vim will now use your custom print character encoding.
|
|
|
|
Vim will report an error with the resource file if you change the order or
|
|
content of the first 3 lines, other than the name of the encoding on the line
|
|
starting %%Title: or the version number on the line starting %%Version:.
|
|
|
|
[Technical explanation for those that know PostScript - Vim looks for a file
|
|
with the same name as the encoding it will use when printing. The file
|
|
defines a new PostScript Encoding resource called /VIM-name, where name is the
|
|
print character encoding Vim will use.]
|
|
|
|
==============================================================================
|
|
5. PostScript CJK Printing *postscript-cjk-printing*
|
|
*E673* *E674* *E675*
|
|
|
|
Vim supports printing of Chinese, Japanese, and Korean files. Setting up Vim
|
|
to correctly print CJK files requires setting up a few more options.
|
|
|
|
Each of these countries has many standard character sets and encodings which
|
|
require that both be specified when printing. In addition, CJK fonts normally
|
|
do not have the concept of italic glyphs and use different weight or stroke
|
|
style to achieve emphasis when printing. This in turn requires a different
|
|
approach to specifying fonts to use when printing.
|
|
|
|
The encoding and character set are specified with the 'printencoding' and
|
|
'printmbcharset' options. If 'printencoding' is not specified then 'encoding'
|
|
is used as normal. If 'printencoding' is specified then characters will be
|
|
translated to this encoding for printing. You should ensure that the encoding
|
|
is compatible with the character set needed for the file contents or some
|
|
characters may not appear when printed.
|
|
|
|
The fonts to use for CJK printing are specified with 'printmbfont'. This
|
|
option allows you to specify different fonts to use when printing characters
|
|
which are syntax highlighted with the font styles normal, italic, bold and
|
|
bold-italic.
|
|
|
|
No CJK fonts are supplied with Vim. There are some free Korean, Japanese, and
|
|
Traditional Chinese fonts available at:
|
|
|
|
http://examples.oreilly.com/cjkvinfo/adobe/samples/
|
|
|
|
You can find descriptions of the various fonts in the read me file at
|
|
|
|
http://examples.oreilly.de/english_examples/cjkvinfo/adobe/00README
|
|
|
|
Please read your printer documentation on how to install new fonts.
|
|
|
|
CJK fonts can be large containing several thousand glyphs, and it is not
|
|
uncommon to find that they only contain a subset of a national standard. It
|
|
is not unusual to find the fonts to not include characters for codes in the
|
|
ASCII code range. If you find half-width Roman characters are not appearing
|
|
in your printout then you should configure Vim to use the Courier font the
|
|
half-width ASCII characters with 'printmbfont'. If your font does not include
|
|
other characters then you will need to find another font that does.
|
|
|
|
Another issue with ASCII characters, is that the various national character
|
|
sets specify a couple of different glyphs in the ASCII code range. If you
|
|
print ASCII text using the national character set you may see some unexpected
|
|
characters. If you want true ASCII code printing then you need to configure
|
|
Vim to output ASCII characters for the ASCII code range with 'printmbfont'.
|
|
|
|
It is possible to define your own multibyte character set although this
|
|
should not be attempted lightly. A discussion on the process if beyond the
|
|
scope of these help files. You can find details on CMap (character map) files
|
|
in the document 'Adobe CMap and CIDFont Files Specification, Version 1.0',
|
|
available from http://www.adobe.com as a PDF file.

6. PostScript Printing Troubleshooting *postscript-print-trouble*
|
|
*E621*
|
|
Usually the only sign of a problem when printing with PostScript is that your
|
|
printout does not appear. If you are lucky you may get a printed page that
|
|
tells you the PostScript operator that generated the error that prevented the
|
|
print job completing.
|
|
|
|
There are a number of possible causes as to why the printing may have failed:
|
|
|
|
- Wrong version of the prolog resource file. The prolog resource file
|
|
contains some PostScript that Vim needs to be able to print. Each version
|
|
of Vim needs one particular version. Make sure you have correctly installed
|
|
the runtime files, and don't have any old versions of a file called prolog
|
|
in the print directory in your 'runtimepath' directory.
|
|
|
|
- Paper size. Some PostScript printers will abort printing a file if they do
|
|
not support the requested paper size. By default Vim uses A4 paper. Find
|
|
out what size paper your printer normally uses and set the appropriate paper
|
|
size with 'printoptions'. If you cannot find the name of the paper used,
|
|
measure a sheet and compare it with the table of supported paper sizes listed
|
|
for 'printoptions', using the paper that is closest in both width AND height.
|
|
Note: The dimensions of actual paper may vary slightly from the ones listed.
|
|
If there is no paper listed close enough, then you may want to try psresize
|
|
from PSUtils, discussed below.
|
|
|
|
- Two-sided printing (duplex). Normally a PostScript printer that does not
|
|
support two-sided printing will ignore any request to do it. However, some
|
|
printers may abort the job altogether. Try printing with duplex turned off.
|
|
Note: Duplex prints can be achieved manually using PS utils - see below.
|
|
|
|
- Collated printing. As with Duplex printing, most PostScript printers that
|
|
do not support collating printouts will ignore a request to do so. Some may
|
|
not. Try printing with collation turned off.
|
|
|
|
- Syntax highlighting. Some print management code may prevent the generated
|
|
PostScript file from being printed on a black and white printer when syntax
|
|
highlighting is turned on, even if solid black is the only color used. Try
|
|
printing with syntax highlighting turned off.
|
|
|
|
A safe printoptions setting to try is: >
|
|
|
|
:set printoptions=paper:A4,duplex:off,collate:n,syntax:n
|
|
|
|
Replace "A4" with the paper size that best matches your printer paper.

7. PostScript Utilities *postscript-print-util*
|
|
|
|
7.1 Ghostscript
|
|
|
|
Ghostscript is a PostScript and PDF interpreter that can be used to display
|
|
and print on non-PostScript printers PostScript and PDF files. It can also
|
|
generate PDF files from PostScript.
|
|
|
|
Ghostscript will run on a wide variety of platforms.
|
|
|
|
There are three available versions:
|
|
|
|
- AFPL Ghostscript (formerly Aladdin Ghostscript) which is free for
|
|
non-commercial use. It can be obtained from:
|
|
|
|
http://www.cs.wisc.edu/~ghost/
|
|
|
|
- GNU Ghostscript which is available under the GNU General Public License. It
|
|
can be obtained from:
|
|
|
|
ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/gnu/
|
|
|
|
- A commercial version for inclusion in commercial products.
|
|
|
|
Additional information on Ghostscript can also be found at:
|
|
|
|
http://www.ghostscript.com/
|
|
|
|
Support for a number of non PostScript printers is provided in the
|
|
distribution as standard, but if you cannot find support for your printer
|
|
check the Ghostscript site for other printers not included by default.
|
|
|
|
|
|
7.2 Ghostscript Previewers.
|
|
|
|
The interface to Ghostscript is very primitive so a number of graphical front
|
|
ends have been created. These allow easier PostScript file selection,
|
|
previewing at different zoom levels, and printing. Check supplied
|
|
documentation for full details.
|
|
|
|
X11
|
|
|
|
- Ghostview. Obtainable from:
|
|
|
|
http://www.cs.wisc.edu/~ghost/gv/
|
|
|
|
- gv. Derived from Ghostview. Obtainable from:
|
|
|
|
http://wwwthep.physik.uni-mainz.de/~plass/gv/

|
7.3 PSUtils
|
|
|
|
PSUtils is a collection of utility programs for manipulating PostScript
|
|
documents. Binary distributions are available for many platforms, as well as
|
|
the full source. PSUtils can be found at:
|
|
|
|
http://knackered.org/angus/psutils
|
|
|
|
The utilities of interest include:
|
|
|
|
- psnup. Convert PS files for N-up printing.
|
|
- psselect. Select page range and order of printing.
|
|
- psresize. Change the page size.
|
|
- psbook. Reorder and lay out pages ready for making a book.
|
|
|
|
The output of one program can be used as the input to the next, allowing for
|
|
complex print document creation.
|
|
|
|
|
|
N-UP PRINTING
|
|
|
|
The psnup utility takes an existing PostScript file generated from Vim and
|
|
convert it to an n-up version. The simplest way to create a 2-up printout is
|
|
to first create a PostScript file with: >
|
|
|
|
:hardcopy > test.ps
|
|
|
|
Then on your command line execute: >
|
|
|
|
psnup -n 2 test.ps final.ps
|
|
|
|
Note: You may get warnings from some Ghostscript previewers for files produced
|
|
by psnup - these may safely be ignored.
|
|
|
|
Finally print the file final.ps to your PostScript printer with your
|
|
platform's print command. (You will need to delete the two PostScript files
|
|
afterwards yourself.) 'printexpr' could be modified to perform this extra
|
|
step before printing.
|
|
|
|
|
|
ALTERNATE DUPLEX PRINTING
|
|
|
|
It is possible to achieve a poor man's version of duplex printing using the PS
|
|
utility psselect. This utility has options -e and -o for printing just the
|
|
even or odd pages of a PS file respectively.
|
|
|
|
First generate a PS file with the 'hardcopy' command, then generate new
|
|
files with all the odd and even numbered pages with: >
|
|
|
|
psselect -o test.ps odd.ps
|
|
psselect -e test.ps even.ps
|
|
|
|
Next print odd.ps with your platform's normal print command. Then take the
|
|
print output, turn it over and place it back in the paper feeder. Now print
|
|
even.ps with your platform's print command. All the even pages should now
|
|
appear on the back of the odd pages.
|
|
|
|
There are a couple of points to bear in mind:
|
|
|
|
1. Position of the first page. If the first page is on top of the printout
|
|
when printing the odd pages then you need to reverse the order that the odd
|
|
pages are printed. This can be done with the -r option to psselect. This
|
|
will ensure page 2 is printed on the back of page 1.
|
|
Note: it is better to reverse the odd numbered pages rather than the even
|
|
numbered in case there are an odd number of pages in the original PS file.
|
|
|
|
2. Paper flipping. When turning over the paper with the odd pages printed on
|
|
them you may have to either flip them horizontally (along the long edge) or
|
|
vertically (along the short edge), as well as possibly rotating them 180
|
|
degrees. All this depends on the printer - it will be more obvious for
|
|
desktop ink jets than for small office laser printers where the paper path
|
|
is hidden from view.
|
|

|
|
8. Formfeed Characters *printing-formfeed*
|
|
|
|
By default Vim does not do any special processing of formfeed control
|
|
characters. Setting the 'printoptions' formfeed item will make Vim recognize
|
|
formfeed characters and continue printing the current line at the beginning
|
|
of the first line on a new page. The use of formfeed characters provides
|
|
rudimentary print control but there are certain things to be aware of.
|
|
|
|
Vim will always start printing a line (including a line number if enabled)
|
|
containing a formfeed character, even if it is the first character on the
|
|
line. This means if a line starting with a formfeed character is the first
|
|
line of a page then Vim will print a blank page.
|
|
|
|
Since the line number is printed at the start of printing the line containing
|
|
the formfeed character, the remainder of the line printed on the new page
|
|
will not have a line number printed for it (in the same way as the wrapped
|
|
lines of a long line when wrap in 'printoptions' is enabled).
|
|
|
|
If the formfeed character is the last character on a line, then printing will
|
|
continue on the second line of the new page, not the first. This is due to
|
|
Vim processing the end of the line after the formfeed character and moving
|
|
down a line to continue printing.
|
|
|
|
Due to the points made above it is recommended that when formfeed character
|
|
processing is enabled, printing of line numbers is disabled, and that form
|
|
feed characters are not the last character on a line. Even then you may need
|
|
to adjust the number of lines before a formfeed character to prevent
|
|
accidental blank pages.
