How to Choose a Receipt Printer
Receipt printers are simple hardware with one genuinely unforgiving decision: the interface has to match what your point of sale software expects. Get that wrong and the printer is perfect, fast, and useless. Everything else — speed, paper width, cutter — is comfort.
Four questions, in order
- What does your POS support? Interface and driver come first, before any other spec.
- Where does it sit? A dry counter, or a hot greasy kitchen. This decides thermal or impact.
- What paper width? 80mm is standard for retail; 58mm suits small footprints. Changing later means new stock.
- Does it need to cut? An auto-cutter is the difference between a queue moving and a queue waiting.
Point of sale platforms support specific printer models and interfaces, and some cloud POS systems only work with a short approved list. A printer that is technically excellent and not on that list will not print. Check your POS vendor's supported hardware page against the exact model number first — this is the single most common receipt printer purchasing mistake and it is completely avoidable.
Thermal or impact
Thermal printers apply heat to coated paper. There is no ink or ribbon, they are near-silent, and they are fast. Impact printers strike an inked ribbon against ordinary paper, which is slower and noisier but survives conditions thermal cannot.
| Thermal | Impact (dot matrix) | |
|---|---|---|
| Best for | Retail, front counter, hospitality bills | Kitchens, and anywhere hot or greasy |
| Speed | Very fast, effectively silent | Slow and audible |
| Consumables | Paper only | Paper and ribbon |
| Heat tolerance | Poor — the paper darkens near heat | Excellent |
| Longevity of the print | Fades over months to years | Stable for years |
| Multi-part copies | No | Yes, with carbonless stock |
| Watch out for | Receipts left in a car or near a grill | Ribbon replacement, noise at the counter |
Thermal paper darkens with heat, and a kitchen pass is hot, humid, and greasy. A thermal ticket there can turn unreadable within minutes. If you are printing order tickets in a kitchen, use an impact printer and accept the noise — it is the one place where the older technology is unambiguously correct.
Interfaces
| Interface | When it is right |
|---|---|
| USB | A printer attached to one till PC. Simple and reliable. The printer is only available to that machine. |
| Ethernet | Shared printers, kitchen printers driven from multiple tills, and most cloud POS setups. The right default for anything beyond a single station. Needs a reserved IP address. |
| Serial | Legacy POS systems. Still common in older installations. Only choose it if the software specifically requires it. |
| Bluetooth | Tablet-based POS and mobile ordering. Convenient; pairing is one more thing to manage. |
| Wi-Fi | Where cabling is impractical. Least reliable of the options under load, and a busy counter is exactly where you do not want that. |
Some models expose more than one interface, which is worth paying for when you are not certain how the counter will be laid out in two years.
Paper width and roll size
Roll diameter matters more than people expect. A printer that accepts a larger roll gets reloaded less often, which at a busy counter is a real saving in interruption.
Cutters and other hardware you will actually notice
- Auto-cutter. Cuts the receipt cleanly on completion. On any counter with a queue this is not optional — tearing by hand is slow and looks careless.
- Drop-in paper loading. Open the lid, drop the roll, close. Compared with threading a path, this is the difference between a five-second reload and a two-minute one by someone who does it rarely.
- Cash drawer port. Most receipt printers trigger the drawer. Confirm the printer has the port and the cable matches your drawer.
- Spill resistance. Counters get drinks spilled on them. Some models are built for it.
- Wall or vertical mounting. Useful where counter space is scarce, but confirm the model supports the orientation.
- Multifunction models combine receipt printing with slip or cheque printing and endorsement, which suits banking, pharmacy, and hospitality back office.
Thermal print is not permanent. Heat, sunlight, and contact with some plastics accelerate fading, and a receipt kept in a wallet or car can become unreadable within months. For anything that has to survive — warranty documentation, expense records, signed card slips — plan to keep a digital copy rather than relying on the paper. This is worth telling customers who ask, and it is a reason some businesses still print duplicates on impact printers.
Speed, and why it matters less than the spec sheet suggests
Receipt printers are quoted in millimetres per second. Modern thermal units are fast enough that print speed is rarely the bottleneck — a typical receipt is out in a couple of seconds at any current speed rating.
What actually determines counter throughput is how quickly the printer starts after the POS sends the job, how fast the cutter operates, and how often someone has to reload paper. A faster rating on a printer with a small roll capacity is a poor trade.
A shortlist that avoids the usual regrets
- Check your POS vendor's supported hardware list and shortlist only from it.
- Choose the interface your POS expects, preferring Ethernet for anything shared.
- Pick thermal for the counter, impact for the kitchen.
- Standardize on one paper width across every station.
- Require an auto-cutter on any customer-facing position.
- Check roll capacity, not just print speed.
- Confirm the cash drawer port and cable if you use a drawer.
Standardizing on a single model across stations means one spare covers every till, one paper width, one driver, and one set of instructions. A counter with a dead printer during a busy period is an immediate revenue problem, and a shelf spare that simply swaps in is worth far more than the small saving from buying whatever was cheapest each time.
Official manufacturer resources
Interfaces, paper width, and POS compatibility vary by exact SKU — the same model family often ships in several interface variants. Confirm against the datasheet for the specific part number.
