I have a problem and I need some help - I think I'm looking in the right direction however could use some additional opinions.
I have an HP Laserjet 4250 that began acting up today. Network printer, etc. The problem: jobs stuck in queue, not responding to pings, etc. I tested/changed patch cables, cold reset of printer, reconfigured internal jet direct card, etc. The problem is odd for the following reasons:
If I reset the printer, it's pingable for a few minutes, even capable of printing docs. That is until about 5 minutes of being idle and inactivity. If it's inactive for x amount of time, all jobs become stuck in queue. I can ping the printer and it responds once, then all others timeout. If I wait a few more minutes and ping again, it responds once, then times out. And so on.
Quick note - I had an old HP Laserjet 2200 with the same problems on the same switch last week. I ordered a new Jet Direct Card b/c old printer, old card, etc. Maybe the JD card isn't the problem?
The 4250 is brand new - only 1 month old (and under warranty).
Anyway, I moved the LJ to a separate, independent hub to test. I had only the LJ and a pc on this hub - not connected to the network. Configured both to be on the same subnet. The LJ never lost it's connection and was pingable and printable the entire time. The hub I used was a little NetGear switch. I tested at various time intervals for about an hour. No problems and printer worked normally.
Therefore, I believe the switch to be the culprit. Switch - CISCO CATALYST 3550
I need some help at this point - suggestions, ideas, etc. I'm functional within cisco envirnoment, however not sure where to look (or what/how to change).
What do you guys (and gals) think?
