QR code not printing 追蹤
I'm trying to set up a QR code on our labels, but when we try to print nothing prints. I know the printer works, because I can change the QR to a normal bar code and it works fine. But when i change it to a QR code or a mini QR nothing prints. We're using Datamax M Class printers and bartender version 7.74.
Any help would be helpful.
