Running iprint on oes11 server, fully patched.

Recently placed an HP m602 printer using HP's universal pcl6 v5.4 for
windows 7.

Seems to work ok, except if a lot of jobs get pushed to it in a short
time frame, some of the jobs end up not printing, and a message comes
up on the printer lcd screen to restart the printer.

By a lot of jobs, I mean not too many, as this printer has only
processed 185 jobs since midnight today, 24 in the last 40 minutes.

Any ideas, suggestions?
