This one has me totally stumped. So we've moved to Kyocera from Xerox, but still have a few Xerox 4510's around. Everything was fine until last week the Xerox printers started to take 30-60 seconds to spool even small single page jobs. Once the job spools it spits out 16 pages of my test pdf fine, just the initial print is slow.
My printer server was still 2008 so I decided to toss up a VM on 2012 R2 and migrate. Printed to the freshly mapped xerox machines on latest drivers....same issue.
Here is what I've tried. Tried different drivers PS, PCL5, PCL6. Tried direct to printer. Mapped to IP as local port in case it was the server. All of this resulted in the same behavior.
Hooking up a USB and being sure to use the same driver, works fine so it doesn't appear to be a driver issue.
This behavior is the same for 3 different 4510s in 3 different buildings on different clients on different switches. Only thing I can possibly guess would be that my switches are causing an issue??? But only for Xerox??? The Kyocera's are all fine, you can hear them printing within a second or 2 at most, and they are on the same network equipment as well.
I don't even know where to go from here, switches are ubiqiti edgemax.
In particular, look at the settings enclosed in green in the image below:
