Everything is set up in Settings > Printers and hardware. Each tablet or phone keeps its own printers: if you have two registers, set up each one.
Which printers work
ESC/POS thermal receipt printers of 58 mm or 80 mm, which are most point-of-sale printers. They connect in these ways:
| Connection | When |
|---|---|
| Bluetooth | Portable or counter printers. Pair it first in Android’s Bluetooth settings |
| USB | Connected to the tablet with a cable |
| Network (IP) | Over Wi-Fi or a network cable, on port 9100. The tablet and the printer must be on the same network |
| Built-in printer | Devices with a printer included, such as some Sunmi or iMin |
| Serial port or USB-serial adapter | Older printers with an adapter (CH340, CP210x, FTDI) |
Set up step by step
- Tap “Set up a printer step by step”.
- How does it connect? Choose the connection.
- Choose the printer from the list. For network, enter the IP or tap “Detect equipment”.
- Paper width: 58 mm or 80 mm.
- Test page: check that it prints correctly.
- What is it for?: Receipts, Kitchen or Receipts and kitchen.
You can also use “Add printer” and fill in the details by hand. On each printer you choose the “Stations it prints” (Kitchen, Bar…) and test it with “Print test”.
Built-in printer
If your device has a printer and it does not respond with “Built-in printer”, try “Serial port (built-in printer)”. Write to us with the model if neither works.
Cash drawer
The drawer connects to the receipt printer. On the printer choose the drawer pin: “Pin 2 (the usual one)”, “Pin 5” or “Both pins”, and tap “Test drawer”. It opens by itself when the receipt of a sale paid in cash is printed (not when reprinting). To open it without a sale use “Open the drawer” at the register: it asks for a reason.
Barcode reader
At the register, a USB or Bluetooth reader that types like a keyboard adds the product when you scan, with nothing to set up. You can also use the camera with “Scan barcode”.
Customer screen
It shows the sale, the total and, if you want, the receipt options to the customer. There are three ways:
- Second screen on the same device: if your device has a screen for the customer, turn it on in “Customer screen” with “Show the sale on the customer screen”. “Show preview” shows you how it looks.
- Another tablet over Wi-Fi: in Settings > Location and devices > Tablets connected over Wi-Fi tap “Pair a tablet”. On the other tablet choose “Customer screen for another register” and enter the code. Both must be on the same Wi-Fi; internet is not needed.
- This same device: “Use this device as a customer screen”. To exit, press and hold the top left corner for 3 seconds.
The customer screen uses the “Customer language” from Settings > Business.
