[rhn-users] Using filters to format print files

[d.qureshi at mdx.ac.uk]

So can I create shell script which will be my filter to fix the step affect problem of my output.
But wish to point the filter to a particular print queue I have created.
Hope this makes sense.

You can easily create a filter using cups.  Create a new backend in /usr/lib/cups/backend.  This can be any executable, including scripts.  What cups will do is pass to this executable everything you need to know about how to get the printed file to parse it.  Your new backend will then show up in your cups configuration as a new printer type.  The following is a little perl script we use to implement a printing dropfolder.
