Should You Use The HP Universal Print Driver or Other Third-Party Print Drivers In XenApp 6?
One of the problems that has plagued Citrix admins and engineers has been third party print drivers. All it takes is for one bad print driver to misbehave, crash the print spooler, and generate dozens of support calls from users who suddenly cannot print.
This common problem led to Citrix including the Citrix Universal Print Driver (Citrix UPD) which is compatible with many popular printers, and is much easier on the Windows print spooler.
