Quick answer:
A receipt printer is the counter device that prints proof of a sale on a narrow continuous roll, and in most stores it also triggers the cash drawer to open. It connects to the till by USB, Ethernet or Bluetooth.
The decision comes down to thermal versus impact. Thermal printers use heat and no ink and suit a shop counter, while impact printers strike a ribbon and survive a hot kitchen where thermal paper would darken. Current models run from about $249 to $369.
You will probably inherit your receipt printer rather than choose it, and that same device can stall a system upgrade later. The printer is also the silent link in the cash drawer: on most counters the drawer connects to the printer, not the till, so a printer choice is a drawer choice.
Here is how the hardware works, which type your store needs, and what it costs to run.
What is a Receipt Printer? The Basics
A receipt printer takes a formatted sale from your POS software and prints it on a continuous roll, then cuts it. The format is fixed by paper width, usually 80mm for a counter printer and 58mm for a portable one. The narrow rolls hold less text per line, which matters for stores with long product names or legally required tax wording.
Most counter printers carry a second port marked for the cash drawer. When the sale completes, the printer sends a pulse down that cable and the drawer springs open. That is the entire mechanism behind a cash drawer on a modern counter.
The consequence: no printer usually means no drawer, so if you decide to skip the printer and email every receipt, check how your drawer will open before the hardware arrives.
Thermal vs Impact Printers
This is the only choice that can be got badly wrong, and it is decided by where the printer will sit rather than what it will print.
| Thermal | Impact (dot matrix) | |
|---|---|---|
| How it prints | Heats chemically treated paper | Strikes an inked ribbon onto plain paper |
| Consumables | Paper only | Paper and ribbons |
| Speed | Fast and near silent | Slow and audibly clattering |
| In heat or steam | Paper darkens, print becomes unreadable | Unaffected |
| Multi-part copies | No | Yes, carbon copies for kitchen and pass |
| Where it belongs | Shop counters, bars, retail tills | Kitchens, prep lines, warehouses |
That fourth row explains why kitchens still use noisy impact printers in 2026. A thermal ticket left near a grill turns black, and a kitchen that can’t read its own tickets stops serving.
Many kitchens have replaced paper tickets entirely with a screen, which is the case for a kitchen display system. Where a printer remains, it should be an impact one.
How Receipt Printers Connect
- USB: simplest and cheapest, tied to one till. Fine for a single counter, awkward for a tablet without a powered hub.
- Ethernet or Wi-Fi: the printer joins your network and any till can send to it. This is what lets one kitchen printer serve three tills.
- Bluetooth: pairs to a tablet or phone. Convenient and the least reliable of the three under load.
- Portable: a battery printer worn on a belt for markets and floor selling. Square lists one at $249.
Network printers are the ones worth paying for if you have more than one till. A USB printer is stranded when its till fails, while a networked printer stays available to whichever register is still working.
The trade is setup. A USB printer works the moment you plug it in, and a network printer needs an address, which is the step that generates most support calls.
What a Receipt Printer Costs to Buy and Run
Consider a cafe with two counter tills and one kitchen printer, comparing a bundled set to buying separately.
Shopify’s OmniLink receipt printer costs $289. Square’s receipt and ticket printer is $369, and Square also offers the Star mPOP, a printer and cash drawer in one housing, at $549.
Buying two Square printers plus a drawer individually pushes past $800 once you add the drawer. The mPOP combination at $549 covers one counter position for less, which is why pairing the two together beats assembling a counter from parts.
Running cost is paper, and it is small but constant. A cafe printing 300 receipts a day gets through rolls steadily, and a store that offers digital receipts typically sees a meaningful share of customers take them, which reduces both the paper bill and the queue.
The takeaway is that the printer is cheap and the counter it implies is not. A $289 printer that needs a $130 drawer and a powered hub is a $450 decision, and pricing the printer alone is how counter budgets get missed. The wider hardware picture sits in what a POS system costs.
Replacement timing is the other cost nobody budgets. Printers are mechanical, and the cutter is the part that fails first. Manufacturers rate it in cuts rather than years, so a busy counter reaches the end of that rating far sooner than a quiet one. A cutter that jams takes the drawer down with it on any counter wired the standard way, which turns a worn consumable into a closed till.
What to Check Before Buying a Printer
Compatibility is narrower here than for any other peripheral, and that is why inherited printers cause trouble. Check the vendor’s supported list by model number, not by brand. Two printers from the same manufacturer often behave differently, and POS apps certify specific models rather than ranges. If you use Shopify, start with the guide on whether any receipt printer works with Shopify.
Check the drawer port. If your counter already has a drawer, the new printer must have the matching connector and pulse voltage or the drawer will simply never open.
Check the paper width against the receipt content. A store printing long product names on 58mm paper produces receipts that wrap awkwardly and confuse customers during a return, which makes the returns process slower than it needs to be.
Check whether an impact printer is genuinely needed. Only heat, steam and grease justify the noise, and a printer at a bar pass usually does not sit in any of them.
Printers Worth Comparing
Printer choice follows your POS vendor more tightly than any other peripheral, so your shortlist is usually short. Square sells the broadest tested range, including the mPOP combination that solves the printer and drawer question in a single purchase. Check Square’s POS hardware for the full list.
Shopify keeps a narrower set, with the OmniLink at $289 as the standard counter option. See the Shopify POS hardware range for compatible models.
If you run a food business, settle the kitchen side before the counter side, because that is where the impact printer requirement appears. The systems built for it are covered in the roundup of POS systems for cafes.
