Description
Some printer drivers can cause server problems when printing to client printers in the Citrix XenApp Server farm. Printing to a client printer with a problematic driver can result in a fatal system error on the server. Because of this, you might need to prevent the auto-creation of client printers that use specific printer drivers. The printer driver compatibility feature allows you to designate or prohibit drivers for use with client printers.
Test methodology
An HP printer was attached to the client system using a parallel cable, USB cable, or TCP/IP port. The printer was installed on the client system and drivers for the printers were downloaded from the HP Driver Support website.
The printer driver mapping and compatibility policy was configured and enabled on the Citrix XenApp Server. The driver for the HP printer was configured to allow the auto-creation of the client printer using that particular HP driver. The client then connected to the Citrix XenApp Server farm and the auto-creation of the client printer was verified. The client printer was able to print successfully.
Subsequently, in the printer driver mapping and compatibility policy, the driver for the HP printer was configured to disallow the auto-creation of the client printer using that particular HP driver. The client then connected to the Citrix server farm and the client printer was not auto-created. There were no issues with preventing the HP printer from being auto-created.
