Problem:
When using Konica Minolta Universal Printer Driver there seems to be no paper source available in TPOG. However you can select entries and via registry you see there are actually trays in TrayData, just the display name is missing within the printer dialog (see images below).
Cause:
Unknown – driver issue with the Konica/Minolta UPD
Workaround:
Use the native printer driver for the printer model instead of the Universal Printer Driver.
