Local Printer Mapping Fails in Citrix Session

Problem

Local printers do not map within a Citrix session. 

Cause

The ThinPrint ICA Client may not start with a XenApp session, typically during the installation or update of relevant components.

An error will appear in the ThinPrint Diagnostics Log:

• Event ID 4002: Can't connect to virtual channel (50)

Applies to product

ThinPrint Engine 10+

ThinPrint Client ICA 10+

Solution

If using the ICA print protocol, ensure the correct installation order of components. Both Citrix Receiver and ThinPrint Client must be installed with administrator rights.

Installation steps:

1. Install Citrix Receiver.

   • For updates or reinstallation, uninstall the existing version and manually delete the folder at C:\Program Files (x86)\Citrix before proceeding.

2. Start a XenApp session.

3. Install ThinPrint ICA Client.

   • After installation, log off from the workstation.

4. Start a new XenApp session.

   • The ThinPrint ICA Client should now start automatically (verify by checking the TP Client icon in the system tray).
