lpr style filter chains

[dietz proepper]

Hi,

I have the following problem (and could not find a
solution on the list.) A lpr setup shall be moved
to something cups based.

In the lpr setup, there exist several queues that
do preprocessing of print jobs, i.e print two pages
to one, posterize A4 to A3 and so on.

Is there an easy way to accomplish something similar
with cups? Either by having different queues that speak
to the same printer and get preprocessed somehow or
by setting some options for print jobs that get evaluated
by a custom filter? Or anyhow else?

Thinks I already thought of but am not really happy include:
- using a preprocessing shell script that is called instead
  of lp (not nice if application printing wants to talk to the
  cups daemon directly)
- leaving the lpr setup in place and have
  it talk to cups (quite idiotic, then we can stick with the setup
  and need no cups ;-)

thx in advance for any advice,
    Dietz
