start a script over printing via cups

Bauder, Alexander — Wed, 22 Sep 2004 03:53:37 GMT

Hey professionals,

I would like to have a printerqueue who only converts PS into PDF. I added a printer in CUPS who generates me the PS - File in /tmp/xxx. That works fine. Then I wrote a script with converts my PS into PDF - This works fine, too.
My Problem is: The script must be started, as soon as a User prints to the printerqueue.

Solve this with cron occurs me badly.
Now my Idea: cups should invoke the script after the PS - File is generated. I tried some badly solutions like modifying the ppd - file from the queue ( insert like `touch /tmp/test`) and so on, but nothing was working.

Any ideas?

Many thanks in advance

Alex

PS: using RH 9.0 on xw4100; working greatly

I do not know if I understant this completely?, but why not try using an alias for lp "cups"
like
my_script
do this
do that
print using cups

in the user profile
alias lp=my_script

or am I not undrstanding your question ?

Hey J-P,
thanks for your reply.

This would work if I had only UNIX - Users, but I will also print from other systems - so I canÂ´t use aliases.
( the printerqueue didnÂ´t recognize the user )
I need an solution who starts my script "after" the lp - command was given and the PS - File was generated.

I was thinking about a while ... true loop
( eg. analyze ll /tmp/$psfile ) - but this continuous loop is sellout...

So I intend to do that with the spoolersystem.

Any ideas how to implement an shellscript, eg. in the modelscript?

PS: I attached the ps2pdf - script, maybe someone is intereste
