vnpstext(1V)vnpstext(1V)NAMEvnpstext - PostScript filter for Vietnamese text printing
SYNTAXvnpstext [-i <prologfile>] [input_8-bit_VISCII_file(s) ...]
DESCRIPTION
The command operates much like the command: it reads a text file from
standard input, and outputs the text in a format suitable for sending
directly to a PostScript printer. A typical invocation is:
% vnpstext 8-bit-vietnamese-file | lpr -PPostScript
expects the Vietnamese font (by default, Courier-VN) to have been down‐
loaded to the PostScript printer. This will be discussed further
below.
Without any arguments, will use the font Courier-VN at 10-point size.
You may change this by specifying an appropriate prolog file. As of
this date (5/92), the prolog files available with vnpstext are
cour10.pro (default), cour12.pro, cour17.pro, cour10b.pro, cour12b.pro,
cour17b.pro, which use Vietnamese Courier fonts at 10-, 12-, and
17-point sizes in normal and bold faces, respectively.
The location of the prolog file can either be the current directory, or
in /usr/local/share/vn-fonts. The latter setting may be overridden by
the environment variable PSLIBDIR.
OPTIONS-i <prologfile> use the specified prolog file instead of generating
the default (cour10.pro).
The prolog file is searched relative to the directory specified by
PSLIBDIR, or the current working directory if PSLIBDIR is not set in
the environment. If the prolog file name starts with the '/' charac‐
ter, it is assumed to be an absolute path name and PSLIBDIR is ignored.
USAGE NOTES
expects the font you use to have been downloaded to the printer. To do
this, send it the appropriate font installation file. As of this date
(5/92), the following are available with initcour.ps and initcourb.ps,
which will download the Vietnamese Courier and Courier-Bold fonts to
the printer. The font sizes are continuously scalable and is specified
in the prolog file.
The downloaded font will persist until the next time the printer is
power cycled. Also, note that the PS engine requires that a password
be supplied for this kind of operation to take place; the password is
normally "0" unless it is changed by the user. This assumption is made
in the init*.ps files. If the printer password is something other than
"0", modify these files accordingly before sending it to the printer.
EXAMPLES
To print out a mail message that contains 7-bit VIQR data, you might
use:
% vn7to8 -m input_file | vnpstext | lpr -PPostScript
The -m option to tells it to start out assuming English mode.
Or if the message contain Viet-Net style Vietnamese but is not neces‐
sarily VIQR-compliant in that it does not explicitly specify the Viet‐
namese language state with the sequence ":
% vn7to8 -v input_file | vnpstext | lpr -PPostScript
Two sample shell scripts are provided to facilitate Vietnamese print‐
ing: and which performs the necessary conversions to print 7-bit VIQR
and 8-bit VISCII data, respectively. See the contents of those shell
scripts for usage details.
RESTRICTIONS
- The line length is limited to 1024 characters.
- Lines are not wrapped. If a line is too long to fit across a
page width, it is truncated (by the printer).
FILES
/usr/local/share/vn-fonts:
default prolog search directory
initcour.ps: Vietnamese Courier font file to download to the
printer.
initcourb.ps: Vietnamese Courier-Bold font file to download to
the printer.
cour*.pro: Various prolog files which specify non-default val‐
ues for font face and size.
