A modified printer filter from the
original a2ps code (4.0) that also counts pages, doesn't core dump. Return
code is number of pages in file (or error)
A modified version of a2ps that acts
as a simple filter to convert ASCII to PS but pass already PS documents
straight through is available here.
hpif is an input filter for HP laserjet style printers. These
printers use DOS style end-of-line determination, so that UNIX machines
(that use newlines) often send them text that goes down and to the
right. This filter will fix that problem with ASCII text jobs, but will
pass preformatted PostScript jobs straight through. (Of course, if your
printer doesn't have a PostScript cartridge, or is not PostScript
capable, then DON'T send it PostScript jobs or you'll end up with a big
mess). It also adds a control-L to the end of PS jobs to force the last
page to eject from the printer. Why do they have to be different!?
Hitler is a fascist printer filter that I wrote. (Please do not
take offense if you are Jewish, I mean no harm). It has several
functions. We use it on one of our PC print servers. First, it
determines if the job is PostScript, PCL, or ASCII. If the job is ASCII
or PCL and has more than 10 binary characters (bytes whose octal value
is less than 7) it is rejected as a binary file. If the job is more than
20,000 characters is is rejected as a file that is too large (possibly a
PS job gone awry). It will save rejected files in /tmp for later
inspection as well. It is not a true input filter, but can be called
from one. Your input filter should send the data to a temporary file.
Hitler will then operate on the temporary file and send its results to
standard output. This is necessary so that it can determine the size of
the file before easily and quickly without processing the entire file.
stripd is a very simple filter that will strip the leading
control-D from PS jobs generated my MS Windows machines. Autocad is
particularly notorious for this, but other apps will have it in there as
well. To be fair, it's Micro$oft's fault and not the application.
printfile is a miscellaneous utility that I wrote to test serial
printers and cables. You hookup the printer, run printfile, followed by
the name of the port and the file, and it will send the file directly
out the port. It also has some switches for controlling baud rate. The
default baud rate is 38400, but you can set it to 19200 or 9600 if you
want via switches. It comes in handy on Solaris machines with that
bloody awful lp print service.
header is a little program I wrote to generate an attractive header
page (generates PostScript). It has the date, user's name, number of
pages they printed, and number of pages they have left (we have
accounting turned on, each user is allocated 100 pages per quarter free,
and must by pages thereafter). It reads the header generated by
berekeley lpd software. So if you store this header in a file (has Job,
etc in it) using the sb directive in your printcap, this program reads
that file to generate the PS banner page.
