Printing with Standard RDP Printer-Mapping Feature
This is commonly used by Remote Desktop users and is equivalent to what you would have with Microsoft Terminal Services.
It can be useful to check this box if you plan on using exotic printers such as receipt printers.
Most of the time it will require that you install the same version of printer drivers on client side and on server in order to work properly.
This means that if your server is a Windows 2008 64 bits and your client computers are installed with Windows XP 32 bits, you will need to install the 32 bits XP Printer Drivers on the server.
Click on the Start Menu, then on Devices and Printers.
Select the Universal Printer or any other printer, to display the Print server properties button at the top of the window:
Once in the Print Server Properties, click on the Driver tab to manually add your (for example) XP 32 bits drivers:
You can of course also directly install your printer drivers using the Printer Manufacturer Website.
It is recommended to check your hardware manual for an installation procedure on terminal server environment.
If you are using USB printers, make sure you updated the RDP protocol of your client computer to 6 or above to ensure maximum compatibility with redirected printers.
For best results, it is also recommended not to use USB printers but prefer COM or LPT printers.
Even with all this in mind exotic printers may not be suitable to be redirected in a TSplus session, therefore you may need to look into specific procedure to install these printers in RDS / terminal server environment, which is very close to TSplus in this case.
If none of the above fits your need, you can also check our add on "USB for RDP" available here: USB for RDP.
