RockPOS supports customers 2 ways to print receipts. They can print receipts by using QZTray or in PDF format.
For PDF format, it’s easy to set up and use. You can use any receipt printer to print.
But for QZTray, we recommend customers to use an Epson printer. This is a good choice! Or you can test your compatibility between your receipt printer and QZTray by testing it at https://demo.qz.io/.
