Pro Series - Invalid Printer Driver Error

When using Pro Series and you encounter the "Invalid Printer Driver" error this may be resolved by changing the default printer that is being connected to your Citrix session. This error seems to occur when a specific printer is selected as the default printer and the driver for that specific printer is not listed on the Citrix server. Simply log-off your current Citrix session and then change the local default printer, then relaunch your Citrix session.
