I am running a print server on Windows Server 2008 R2. When you open the printer properties box, on the general tab, there is a 'Paper Available' box. All the printers pretty much all say 'letter' in that box - some say Letter and Legal and we also have some label printers with odd sizes. Anyway, we have some printers that say 'letter' in that box but the printer is only configured to print legal. We have configured that under Printer Preferences and Printing Defaults - and the printer prints legal just as it should with no issues. However, I have people questioning why it doesn't say legal in that box if it is configured to print legal. In doing a little research I found 2 registry entries that control that box:
HLKM\System\CurrentControlSet\Control\Print\Printers\printername\DsDriver - printMediaReady
HKLM\Software\Microsoft\Windows\NT\CurrentVersion\Print\Printers\printername\DsDriver - printMediaReady
I found if I change this value it will change the value in that box. However, I have some printers where that doesn't happen. I can make the change, close and reopen regedit to verify it is still there, but as soon as I open the printer properties it switches it back to letter. Anyone know why this is happening on some printers and not others or how I can make this change?
