If one is not found the client's printer is not available. You can choose to change this default behavior. The available options are:"Do nothing if one is not found" - If there is a printer driver mismatch the server will attempt to find a suitable driver.

This is the default behavior."Default to PCL if one is not found" - If no suitable printer driver can be found default to the Printer Control Language (PCL) fallback printer driver."Default to PS if one is not found" - If no suitable printer driver can be found default to the PostScript (PS) fallback printer driver."Show both PCL and PS if one is not found" - If no suitable driver can be found show both PS and PCL-based fallback printer drivers.If you disable this policy setting the RD Session Host server fallback driver is disabled and the RD Session Host server will not attempt to use the fallback printer driver.If you do not configure this policy setting the fallback printer driver behavior is off by default.Note: If the "Do not allow client printer redirection" setting is enabled this policy setting is ignored and the fallback printer driver is disabled.
