This is a simple print utility program that I wrote many moons ago.
The syntax of the command is:
print [-f | -c | -lN | -r | -e | -nN] file [file [ file .....] ]
with no arguments at all the program will print a brief summary
of its usage.
With only filename arguments, the program by default prints the
named files using whatever current font, fontsize and number of
lines per page are set in the printer. Usually this is PICA,
10 chars per inch, 66 lines per page. After each file (including
the last) the program prints a carriage return and a line feed.
These defaults can be overridden by using the follwoing options.
The options always apply to all files on the argument line.
If the program sends a command sequence to the printer, it uses
the standard ISO commands. This does not cause a problem even if
you specify, for example, both '-e' and '-r' as the driver will
accept both standard and raw commands.
-f means that the program should NOT print the carriage return and
formfeed at the end of each file ... useful when printing multiple
copies of files that have been formatted and are already an exact
number of pages long or already contain a formfeed at the end of
the file.
-c causes the program to transmit the following command sequences to
the printer and then terminate without printing anything further:
reset (clear), set left margin to 1, set right margin to 80,
set font to PICA, 10 chars per inch, 66 lines per page.
-c exits and does not print any files.
-l sets the number of lines per page to N. If this is not specified
then a line spacing command is not sent to the the printer and
therefore the printer default will be used. This is usually
66 lines per page. If -e (elite) is specified without -lN then
88 lines per page is used. -lN is used to override the default and
does not usually have to be specified. -lN can be used to print
a preformatted file containing labels with a formfeed between each
label.
-r causes 'print' to write the files using raw I/O which
means that all characters go through exactly as in the file.
This allows you to put machine-specific control codes in the
file.
If -r is not specified then the normal device is used and any
escape sequences are assumed to be the standard ISO ones used
by the driver (see include/devices/printer.h for a list of codes)
-e use the elite font (12 cpi AND 88 lines per page) instead of pica.
The 88 lines per page default can be overidden by the -lN option.
For the environmentally conscious, this is a good option to use
when printing program listings since it will save paper by printing
88 lines per page instead of 66. WARNING, saving the environment
may cause you some eyestrain. Life's never easy!
-nN If this option is used then only ONE file should be specified
and that file will be printed N times.
If -e or -lN were specified then after the program has finished
printing all specified files, it will change the default font back
to PICA, 10cpi and 66 lines per page.
BUGS: Yep. The ^C abort does not work properly because the program reads
512 byte chunks at a time from the file and the printer may have
a 1K or larger buffer so that the ^C doesn't take effect immediately,
if at all.
