58mm vs 80mm Receipt Printer Guide for Small Business

⚡ In short

Choose 80mm for shops and restaurants that print itemised receipts with a logo and longer item names, and 58mm for compact counters, food trucks and mobile use. Both are thermal: no ink needed. Browser-based POS systems, including the Socialknocks mini POS, print to any printer your device supports at 58mm, 80mm or A4.

How to choose

Long item names or add-ons? Choose 80mm so lines do not wrap awkwardly.
Tight counter or mobile selling? Choose 58mm for size and portability.
Want your logo on the receipt? Both work, but 80mm gives it more room.
Printing volume: check the printer's speed and paper roll size.
Connection: USB, Bluetooth or Wi-Fi, depending on where it sits.

Thermal printing basics

Thermal printers use heat on special paper, so there is no ink or toner to replace.
Receipts fade over time if stored in heat or sunlight, so keep copies of important ones digitally.
Logos print in black and white, so a simple, high-contrast logo looks best.
Keep a spare roll at the counter.

Printing from a browser-based POS

A browser-based POS prints through your device's print system, so you do not need special drivers from the POS vendor: if your computer or tablet can print to the printer, the POS can too. With the Socialknocks mini POS you choose 58mm, 80mm or A4 in Receipt Settings, and each receipt prints with your logo, address, phone and an itemised table. See the full mini POS overview.

Auto-print without the print dialog

Browsers normally show a print dialog. For hands-free printing at a counter, many shops set the browser to print silently to a default printer (for example Chrome's kiosk-printing mode). That setting is configured on your device, and the in-app help guide in Socialknocks explains the steps. Test it before opening day.

Before you buy

Confirm the printer works with your computer or tablet's operating system.
Print a test receipt from your POS at the paper size you chose.
Check the text is readable and the logo is clear.
Buy a few spare rolls, then buy more printers only after the first one proves itself.

Frequently asked questions

What is the difference between 58mm and 80mm receipt printers?

The paper width. 80mm is the most common for shops and fits more text, while 58mm is more compact for mobile or small counters.

Which is better for a restaurant?

80mm is usually better because itemised receipts with add-ons need more room.

Do thermal printers need ink?

No. They print with heat on special thermal paper.

Will my POS print to any thermal printer?

A browser-based POS prints to any printer your device supports. Test yours first, because compatibility depends on your device and printer.

Can I put my logo on the receipt?

Yes. The Socialknocks mini POS prints your store logo at the top of the receipt.
