How-to · Setting up

Connect a receipt printer and a cash drawer

Set a network printer from your computer, or choose a USB one on the tablet. The drawer plugs into the printer.

A counter's printer prints the receipt and opens the cash drawer. On Setup, Counters and devices takes you to it.

A network printer, from your computer

1. Open Counters, tap Add a device, choose Printer, and choose the counter.
2. Type the printer's address on the network, such as 10.0.1.139. Name it if you like.
3. Choose the Paper width, and under After each sale choose Print a receipt, Ask first, or Don't print for a counter that hands out few.
4. Tap Set the printer.

The counter's Printer line shows the address. The tablet picks it up at its next sign-in: lock it and sign in again with a PIN, and it prints there from then on.

A USB or Bluetooth printer, on the tablet

Do this on the tablet that is the counter. Open Setup on it, tap This tablet, and find Printer on this tablet.

• By USB: plug the printer in. If it is not listed, tap Add a USB printer and choose it.
• By Bluetooth: pair the printer in the tablet's own Bluetooth settings first. It then appears in the list.
• On the network, from the tablet: type the address and tap Add a network printer.

Choose the printer in the list. The line reads "This Merchant Display prints here".

Test it

On the tablet, tap Test print. A short slip prints and the drawer opens.

The slip ends with a numbered line at each width a printer comes in. A line wider than the paper breaks in two. Choose the widest number whose line stayed whole as the Paper width, then test again. Most 80mm printers take 48 characters across; most 58mm printers take 42 or 32.

The cash drawer

The drawer's cable plugs into the socket on the back of the printer, not into the tablet. Nothing to set up: once the counter has a printer, its Drawer line says Opens from the printer. It opens the moment the cashier taps Paid in cash. On a tablet with a printer chosen, Add a device, Cash drawer, Test the drawer opens it once.

With no printer chosen, receipts open in the browser's print window instead.
