Alright, I narrowed down the issue I was having earlier and came up with an entirely new question.

Printer & Drivers for: HP LaserJet 1320n

The duplicate printer error I came across has little or nothing to do with the drivers, it is entirely on Microsoft Retail Management settings. Even after installing the drivers for the printer and making sure that it is printing a single copy it will still send duplicate copies to the printer.

Going through preferences in "Printers and Faxes" the copy preferences are set to print 1 copy.

Going through printer settings in Microsoft RMS the copy preferences are set to print 2 copies.... Yea... and the preferences won't save no matter what I do. I've tried logging in with the managers password, my admin password, and the network/general admin password. None of those will save the settings after closing out the receipt I just printed off.

Any idea's on how I can get the settings to save in the program to reflect each print job afterwords?
