Solution

You would need to follow a few steps in the following order:

1. Log out from Linnworks.net

2. In Virtual Printer client click 'Virtual Printer' > 'Disconnect'

3. Open Task Manager on your PC (right-click on the Taskbar > Task manager) and 'End task' for all LinnPrint jobs that you will see:

4. Log in to Linnworks.net

5. Log in to Virtual Printer

6. Check the log in Virtual printer: it should say 'Connected to print server : eu-printingX.linnworks.net' and the virtual printer logo at the top will be green.

If there are still issues after following the exact steps above, please contact our support.
