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

Symptom

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

Resolution

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
