Multiple copies in selfwritten backend

[Mario Goppold]

Hi List,

today I have been confronted with the following problem :
An extren System put a job with multiple files in one jobid.

localhost:/var/spool/cups # ls -l /var/spool/cups/*268*
-rw------- 1 root lp  630 18. Jul 14:54 /var/spool/cups/c00268
-rw-r----- 1 root lp 6242 18. Jul 14:54 /var/spool/cups/d00268-001
-rw-r----- 1 root lp 6242 18. Jul 14:54 /var/spool/cups/d00268-002
-rw-r----- 1 root lp 6242 18. Jul 14:54 /var/spool/cups/d00268-003
-rw-r----- 1 root lp 6242 18. Jul 14:54 /var/spool/cups/d00268-004
-rw-r----- 1 root lp 6242 18. Jul 14:54 /var/spool/cups/d00268-005

My selfwritten backend gets only /var/spool/cups/d00268-001 as file
to print and the numcopycounter is set to 1. The backend handled
file -001 and the spool remains active with no action.

How can/should I handle this?

My backend is in perl. I can find and print the files but how can
I tell cups that this job is finished.

Many thanks for your upcoming  help.
