Would like to ask if you have any idea with the problem I encountered lately.
In my development machine. GK420T works great and able to print barcodes and label.
But after my deployment, I tested it to one of the end user production machine and its not working.
After printing, a message saying that "Printing Complete" but the printer was not printing anything.
Really need this one to be fixed as this is highly needed by our Production.
Have you checked the status of the printer? The "Printing complete" from the sample code simply means that the printer likely received the print job. It does not really mean that it has verified the print job is complete or that the printer is in a good state to print.
