Printer stops printing after 18 pages

[Philipp Dreimann]

Hello,

i'm running cupsys 1.2.7-4 on Debian Etch with an Samsung CLP-510N and 
the latest unified drivers from Samsung for SPLC support.

I'm using samba to let Windows clients talk to cups and to publish the 
cups drivers to the clients.

When i try to print a document with a pagecount >= 18 every page after 
page 18 doesnt get printed.

I'm seeing messages like "Copying page 51..." in error_log so i guess 
that cups recognised the pagecount correctly.

But they dont get printed correctly.

Can someone give me a hint how to solve this problem?

regards,
  Philipp
