[Printing-user-general] Cups delays after 6 jobs

Hi!

We have a certain problem while printing with cups.
cups stops for app. 1-3 minutes after processing 4-6 jobs which are ready to
print.

I left all settings on default, except: 

Port 631
Browsing Off
MaxJobs 0
MaxClients 1024
PreserveJobHistory No

Does anyone has an hint where to search?

I tried all options in the cupsd.conf which can produce a timout, but the delay
still exists.
Also i tried some other printer drivers - no effect.
At the moment i use a "raw printer" because the jobs are preformatted.



regards,

raphael
