Brand new server (HP ProLiant ML150 G9 - Server 2008 R2) having problems with a USB printer. There are 4 network printers that work great, and a legacy USB printer the owner would like to continue to use. The P2035 must use HP Universal print drivers in 2008 R2, and it worked in the beginning to print one job and then just sit idle. No jobs would be shown in the queue, they would flash quickly like they were sent off to the printer successfully. I tried P2015 and P2050 drivers but only got ASCII code print outs. Tried PCL 5 Universal also. Now I go back to HP Universal PCL 5 and the printer has disappeared from view in the device and printers page. All of the other printers show and continue to work. I have restarted the print spooler several times. If I open a print dialogue box the printer shows up, but I am not attempting to print to it until I see the print queue. It is not possible to restart the server until the evening, which is next on my list. I have removed any instances in registry for that printer, recreated a new printer and the same thing happens. I can create a new printer that is not using USB001 and it appears just fine.
