Restaurant Hardware Knowledge Base — Printers, Terminals and Peripherals

Choosing hardware that lasts a full service

Restaurant hardware fails at the worst possible moment: the middle of a Friday rush. Buying consumer-grade equipment saves money on day one and costs far more in refunds, replacement runs and staff frustration by month six. This knowledge base covers the essential categories, what to look for, and how each device should be configured with the POS.

The rule of thumb is to buy commercial-rated hardware from vendors that publish spare-parts lists. If a device does not have an official parts diagram, it is a consumer product with a restaurant sticker.

Thermal receipt printers

• 80mm width is standard for cashier receipts; 58mm is only for small handheld printers.
• Ethernet (LAN) is preferred over USB for shared cashier printers — no host PC required.
• ESC/POS is the standard command set; check Arabic/RTL support for the Middle East.
• Auto-cutter is worth the cost — hand-tearing paper slows every checkout.
• Cash-drawer kick port (RJ11/RJ12) on the back is required if you want the drawer to open on payment.

Kitchen printers and KDS screens

Kitchen printers must survive heat, humidity and grease. Look for splash-resistant models rated for kitchen use, and place them away from direct steam. Impact printers (dot-matrix) are still common for very hot stations because thermal paper darkens near heat.

A KDS screen replaces most kitchen printers. It reduces paper waste, shows timers and lets stations bump tickets when items are ready. Many kitchens use a hybrid: KDS for the line, a small thermal printer for the expo or pickup station.

Cash drawers

• Steel-body drawers with a media slot last for years of daily use.
• Drawers connect to the receipt printer via RJ11/RJ12 and open on cashier command.
• 5-bill / 6-coin trays fit most currencies; 4-bill trays are cramped for split tender.
• Under-counter mounting brackets stop the drawer from walking during a shift.

Payment terminals and tap-to-pay

Payment terminals are regulated hardware. They must be certified by the local card schemes and the acquirer, and they cannot be replaced casually. Stand-alone countertop terminals are simplest but require manual amount entry; integrated terminals pull the amount from the POS automatically and reduce miskey errors.

Tap-to-pay on phone (Tap to Pay on iPhone, Tap to Pay on Android) is available in some regions and lets a staff phone act as a terminal. It is convenient for pop-up service and pickup but should still be reconciled through the POS.

Tablets, barcode scanners and receipt paper

• Prefer tablets with a real charging cradle, not just a wall charger — cradles keep them upright and always powered.
• 2D barcode scanners read both traditional barcodes and QR codes; useful for loyalty and coupons.
• Buy thermal paper from a reliable supplier and store it away from heat and sunlight — cheap paper fades and jams.
• Keep a spare printer, spare drawer key, spare paper roll and spare power brick on-site. Uptime is the point.

Frequently asked questions

Can I use a home inkjet printer as a receipt printer?

No. Inkjets are slow, smear when wet, and are not designed for continuous receipts. Use a thermal receipt printer.

Do I need one printer per station?

Not necessarily. Many kitchens run one KDS screen per station plus a single expo printer. Small venues can share one printer if routing rules are configured.

How long does thermal paper last on the shelf?

Sealed rolls stored cool and dark last 12–24 months. Printed receipts fade faster; keep long-term records digitally.
