I found this very useful every time I have to deal with drivers in Terminal Servers, the most common scenario is for HP Printers that need a specific PCL driver to work properly, the Easy Print Driver is great because it offers compatibility with most printers but not all features are available and customers want to have the same level of functionality and user experience in RDS that they have when using their local computer (Just remember to modify the GPO to not use Easy Print as the first option, more to come on this)
You can get the full list of switches by executing: | La lista completa de modificadores la encuentras ejecutando el siguiente comando
