The printer prints a test label printout but does not print a printout in the custom application

Hello everyone,

A WinForm application I developed does not print labels on the client computer. I tested it on different computers in my own environment. I also tried it on the virtual Windows 10 operating system, where I did a clean install. I also tried it on my different physical laptop with Windows 11 and a second Windows 10 operating system. In my environment the application works.

The test print runs successfully in the Zebra Printer application on the customer computer. There is no NLOG error log through my application. In NLOG, my TRACE process steps appear as successful. My source code for printing is as follows.

- Driver is installed.
- Zebra Setup Utilities is installed.

No prints appear in the Windows print queue. When the test page is printed in the Zebra application, the process appears in the Windows printer queue.

I don't know what else I can test. I would be glad if you help.

The operating system of the customer computer is Windows 11.

The video recording of the transaction on the customer's computer is attached.

My development printer device:
ZD22042-T0EG00EZ

Client printer device:
Zebra ZD421, connected via USB-cable (Zebra part# ZD4A043-30EM00EZ)
