Print2RDP allows users to have full access to the local printer driver settings. When Print2RDP connects to a printer in the RDP session, on the server side of the Printer preferences dialog only the paper size, orientation, and resolution of the printing can be changed.

However by turning on the printer preferences in the Print2RDP Client the users local printer driver dialog will appear just prior to the print job being sent to the printer. This will allow the user to change options such as printer tray settings and other printing options.
