Why does print job get into queue when I use port monitor on the printer port for an EPSON TMT88V receipt printer?
I have installed EPSON standard Windows driver with printer installed on the physical serial port. I installed port monitor to monitor data on serial port.
After restarting the system when I send a print job it stays in print queue. When I stop the port monitor and print to printer and then start the port monitor it prints properly. I am unable to understand why TM-T88V waits for sample print without port monitor?
It's related to Windows driver programming. Port monitor mentioned in the question is Windows driver created by me.
How can I add minimal reproducible example for Windows driver code? I can't post the code due to company policies.
I just need understanding of why this is happening

1Tough Question. So you have written a Microsoft Windows Device Driver that is not really working correctly. You are not allowed to post the Source Lines of Code that might be erroneous. And still you want us to perform some kind of Imaginary Debug Process. Very Difficult Situation. – None – 2019-11-12T17:31:09.060
This question is not about computer hardware or software, within the scope defined in the help center. If a minimal reproducible code example was provided I would have voted to migrate this to Stack Overflow. However, without an example, I know it would be closed. – Ramhound – 2019-11-12T22:28:25.547
