1316087 - Invalid Printer when running .NET Win Forms application on Citrix


Occasionally on a Citrix server users get Invalid printer from the Print to Printer method in a .NET Win Forms application.  Once one user get this error then the rest of the users start recieving on of the following error messages until a reboot:

  • The Report Application Server failed
  • Load report failed
  • The request could not be submitted for background processing.

Reproducing the Issue

  • Citrix Server
  • Visual Studio 2005 Win Forms application
  • Printer connectede to system through a firewalled VPN connection


The cause is currently not known. We tried the following different possibilities and the customer reported that it is working now:

  • Turn the "No Printer" option on the report in case the report was looking for the original printer
  • Created an application to ping and monitor the printer as the printer was through a firewall and it could be a connection issue.
  • Customer also did work on their firewalls and VPN
