Setting up a thermal receipt printer is a hardware bring-up that happens once per printer, before Rundoo can print receipts to it. This page walks the Star Micronics TSP100IV — Rundoo's recommended model — from box to first test receipt.
For receipt printer issues after the printer is already paired, see Printer troubleshooting.
The standard Rundoo terminal package doesn't include the printer — you order it (along with the cash drawer and paper) yourself when you're set up for cash sales. See Hardware setup for the full register-station gear list.
Set the printer on a flat surface near a power outlet and your network gear. Make sure there's room around it for ventilation and for paper to feed out the front.
To register the printer with Rundoo, you need its IP and MAC address. Both print on the network configuration sheet.
