Linux script related to printer


Is it possible in a Linux system with cups insert a script related to a specific printer (special/virtual) so to write its content on a file before print it?

you can add a shell script as a filter and you can save the file and also send back to cups for processing. Or you can modify the original plain text filter to save files.

http://eloquence.marxmeier.com/sdb/html/1123683643.html

see the trivial example:
Code:
#! /bin/sh

# Command line arguments
job="$1"
user="$2"
title="$3"
numcopies="$4"
options="$5"
filename="$6"

# Pass through
cp "$filename" "<saved filename>" # < new line
cat "$filename"

Thanks for you response.

I have some question:
1) In what directory should I create the script? (/ etc / cups / interfaces?, but currently this directory is empty although there are several printers installed)
2) How do I configure the ppd file in order to get him to use the script ?

Thanks for your help.

I tried it and it works. The problem is that it writes a file in postscript format, while I wish it were plain text.

Thanks for your help.

That is because the test page is Postscript. Since the filter will not convert file formats what are you trying to accomplish?

I have tried to print out a page of plain text, but I always get postscript.
I want to get two things:
print the file and store the file printed.

Thanks for your help.

This is normal. What application are you using to create/open the file? It depends on the application but most will generate a PS file when you select to print. So in fact you are storing the file printed. If you want the stored file to be readable you could convert it to PDF in your filter.

I can't accomplish this since my goal is to provide file in pure raw text with print to a
program for processing
