Symptoms

When going to File Processor, you are unable to select a specific printer in the Print output. The printer itself is accessible and visible in Windows Printers & Devices.

Cause

A possible cause could be that the File Processor is running under a specific user (e.g. FPUser) but the current logged in user (e.g. User1) who installed the printer is a different one. There is a possibility that the user FPUser doesn't have access to the printer, because the printer is installed only for User1 and not for FPUser. Or the printer isn't rolled out to that specific user.

Resolution

Solution 1:

1. Open Windows services (CTRL+R services.msc)
2. Stop the Winking File Processor service
3. Right mouse-click the service and select Properties and change the Log On account. Make sure you select a user that has access to the printer.

Solution 2:

Make the specific installed printer available (permissions) for the user that is running the Winking File Processor service.
