Hello, we have been suddenly started to have problems with printing on fully
patched OES2 Linux cluster:

All printers have Printer Agent Status Details: SNMP Communication Failed
Some printers print well, but other printers just print out few first pages
and stop the job.

Print manager's status seems to be all OK. But in /var/log/messages, these
lines are being from time to time printed:

Apr 27 11:25:09 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ1500n 12', Error 11
Apr 27 11:26:44 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ 3030', Error 2
Apr 27 11:26:55 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ 3030', Error 2

Apr 27 12:05:11 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ1500n 13', Error 9
