I have a number of network printers within my network. Network is gigabit through multiple Cisco SG500-52 switches. The printers that I seem to be having the most complaints about are Ricoh MP2352 copiers. User A will hit print and nothing, having the wait time be anywhere from 5 to 30 minutes. User B will print (say 10 minutes later) and User A's prints will come out as well as User B. You can ping the IP with no problems and no network problems to be seen. Have tried updating drivers, changing the Ip address on the copier (in case it was in conflict with another machine for some mysterious reason, and tried turning autotuning off as I saw recommended in a couple of posts from others).
I'm stymied as to where else to look, so if anyone can point me in a direction to look I would be grateful.
