A USB printer plugs straight into one tablet, with no network setup. It prints for that tablet's checkout station only: other tills at the location can't reach it. If several tills need the same printer, connect it to your network instead (see Connect a printer to your network).
Before you start
An Android tablet as the till. iPads can't use a USB printer.
A receipt printer with a USB port. Epson TM and Star printers work.
The right cable. The tablet has to be in charge of the printer, which needs one of these:
a USB-C to USB-B cable: the USB-B end is the square-ish plug that goes into the printer, or
the printer's own USB cable plus a USB-C OTG adapter (USB-C plug to a USB-A socket) on the tablet.
A manager's passcode for the till. A cashier can't finish the setup.
A roll of paper in the printer.
Note: Use the printer's USB-B port, the one meant for a computer. Many Epson printers also have a flat USB-A port for a scanner or a customer display. A tablet plugged into that port can't print.
If the tablet must charge while it prints, use a powered USB hub between the tablet and the printer.
1. Add the printer in the Vireno console
In the console, open Settings > Devices and choose the location.
Select Add device, then Receipt printer or Kitchen printer.
Choose USB.
For Which checkout station is it plugged into?, choose the checkout station of the tablet you'll plug it into.
The printer is added and shows Test on a till.
For a receipt printer, you can do the same from the checkout station: select Pair devices and, on the receipt printer step, choose USB printer on this station.
2. Plug the printer into the tablet
Connect the printer to the tablet with the cable from Before you start.
Switch the printer on.
If the tablet asks whether Vireno may use the printer, or whether to open Vireno when it's connected, tap OK. Tick Always if it's offered, so it doesn't ask again.
3. Finish the setup on the till
On that tablet, open Settings > Printers. The printer is listed with Set up.
Select Set up and choose the make: Star, or Another make (Epson, Xprinter…).
Under Which printer is it?, choose your printer. If the tablet asks to let Vireno use it, tap OK.
Select Print test page.
Answer the questions from what came out on the paper:
Which ruler reached the right edge?
Which number printed the letters of your language right? If none of them look right, choose None of them, and the printer prints those letters as a picture instead.
Did the paper cut?
Did the cash drawer open? Choose No, or there is none if there is no drawer cabled to the printer.
Select Save and ask a manager to enter their passcode.
The till says the printer is ready, and the console shows it as Ready.
To choose whether receipts print on their own, ask the cashier or never print, open the checkout station in the console and select Pair devices. Print receipts is on the last step.
If something goes wrong
"Plug the printer into this tablet and turn it on." The tablet doesn't see a printer.
Check the printer is switched on.
Check the cable goes into the printer's USB-B port, not a USB-A port.
Check the cable carries data: many USB-C cables only charge. Try the cable that came with the printer, with an OTG adapter.
Unplug the cable, plug it back in, and select Look again.
"This tablet isn't allowed to use the printer yet." The tablet asked whether Vireno may use the printer and the answer was no, or nobody answered. Choose the printer again and tap OK.
"Couldn't find the printer." The cable came out or the printer is off. Check both, then print again.
"The printer stopped partway." The printer didn't take the slip. Check the paper and that the cover is shut, and that the printer's error light is off. If it keeps happening, unplug the cable, switch the printer off and on, plug it back in, and try again.
The printer runs out of paper. The till can't tell, and may say a receipt printed when nothing came out. Keep a spare roll near the printer.
You replace the printer with another one. Plug the new one in and select Set up on the old printer's entry. The till offers the new printer and says it takes the place of the old one.
Receipts don't print after a sale, and the till offers the card terminal instead. The printer isn't set up yet on this tablet, or it was added to another checkout station. Finish step 3 on this tablet, or check the checkout station in step 1.
