Citrix Print Manager Service is not running
The Citrix Print Manager Service is part of the Citrix Virtual Desktop Agent (VDA) software which runs on a single or multi session machine. It is used for the Citrix Advanced Universal Printing Architecture. It takes care of the client printer mappings between a user client and the VDA within an ICA session. This service heavily relies on the Windows Print Spooler service which spools print jobs and handles interaction with the printer.
