I have activated the Print Server role on my Windows Server 2012 R2 Standard server and added a new HP Officejet Pro X476dw, deployed to the clients via Group Policy. The printer is setup with preprinted A4 paper in Tray 1 (Manual Feed) and plain A4 in Tray 2. Everything works fine except when printing to Tray 1 from a client, the printer displays a prompt saying that the paper size or type is mismatched (it says "Insert A4 - Preprinted"), which is to be confirmed with "OK" before the job is actually started.
I have search the web for this problem, in many cases the answer is to select media type "Any" ord "Unspecified" in "Printing Defaults" on the "Advanced" tab in the printer's properties on the server. However, I do not have any of these options, so I set it to "Preprinted".
Any ideas? Thanks!
