How to force Printer redirection in an RDP Session

Post by Mikethetech »

In OS's other than Server2003, printers that use non-standard ports for printing aren't redirected during an RDP session.
To force all ports (including DOT4) on the client computer to be filtered for redirection:
In the registry editor:
Add a DWORD value named FilterQueueType to HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default\AddIns\RDPDR and set its value data to FFFFFFFF.

If it's a multi-function device (e.g. scanner/fax/printer combo):

Change the port that the multifunction print device uses from DOT4 to an LPT port.

To force the multi-function printer to use LPT1
Go into the printer properties, click the Ports tab, click an LPT port, and then click Apply.

The printer should now appear next to that port.
4. Close the Printer Properties window, and then reconnect the RDP session.

Be aware that it loses its all-in-one capabilities, such as scanning, faxing, or copying when set to LPT rather than DOT4
