Connect a receipt printer to your POS

Each register can have its own receipt printer. You can print to an Epson receipt printer from the web register, to a Wi-Fi thermal printer or AirPrint from the iPad app, or to any printer through the browser print dialog. A cash drawer plugged into the printer can open on cash sales.

Pick the right receipt printer option

Print dialog (any printer) works with any printer your computer or tablet can already print to, including A4 printers and Save as PDF. The register opens the print window and you press Print. The receipt is laid out for 80 mm paper.

Epson receipt printer is for the web register. It prints straight to an Epson printer that supports ePOS-Print, with no print window.

Wi-Fi receipt printer is for the Mawg3 POS app on iPad and iPhone. It works with Epson TM, Star in ESC/POS mode, Xprinter and most thermal printers on port 9100.

How to set up a receipt printer for the web register

  1. Connect the printer to the same Wi-Fi or network as the register. Print the printer's self-test page to find its IP address.
  2. In your admin, open Point of Sale, then Settings, and click Manage next to Devices.
  3. Next to the register, click the printer button, Printer & cash drawer.
  4. Under Printer, choose an option.
  5. For an Epson printer, enter the Printer IP address and choose a Paper width of 80 mm or 58 mm.
  6. Tick Print a receipt after every sale if you want receipts to print on their own.
  7. Tick Open the cash drawer on cash sales if your drawer plugs into the printer.
  8. Click Save.

Extra step for Epson printers

Turn on ePOS-Print in the printer's settings. Then, on the register device, open https:// followed by the printer's IP address in the same browser, and accept the printer's certificate. You only do this once per device. If you skip it, the browser blocks the printer and nothing prints.

Set up a printer in the iPad or iPhone app

  1. In the Mawg3 POS app, open Menu, then Printer.
  2. Choose Print dialog (AirPrint) or Receipt printer on Wi-Fi.
  3. For a Wi-Fi printer, type its IP address and choose the paper width.
  4. Turn on Print a receipt after every sale and Open the cash drawer on cash sales if you want them.
  5. Tap Save, then Test print to check it works. Use Open drawer to test the cash drawer.

Tips if nothing prints

Check that the printer and the register are on the same network. Ask whoever manages your router to give the printer a fixed IP address, so it doesn't change after a power cut. If you see Printer not connected, try the Print dialog option to confirm the receipt itself is fine.
