Printing to IP Printer

O/S: AIX 4.3.3
Printer: Fujitsu 6600
1 Blk = 512K

When sending a job to the printer (setup as an IP printer) that is around 20 blocks or more the job gets requeued and then the printer goes down. The job is usually in the second copy of the output when this occurs. Any jobs that is less that 20 blocks prints OK. This occurs on 3 printers of the same brand… I am in a deep discussion that it may be on the printer side and not the server side…but…I need to prove them wrong..

Any help would be appreciated.
TIA.
