The short answer
Most retail counters need a thermal receipt printer, a cash drawer that opens on sale, and a barcode scanner. Grocery and delis add scales. Kitchens add a heat-resistant kitchen printer or a display screen. Buy business-grade — consumer hardware fails under retail duty cycles.
Thermal printers and connectivity
Thermal printers avoid ink costs entirely. Choose ethernet or USB over Bluetooth for fixed counters — Bluetooth pairing failures cost more minutes over a year than the connection ever saves.
Digital receipts
Emailed and texted receipts cut paper cost, capture a contact detail with consent, and reduce disputes because customers can find the transaction later. Offer both.
Key takeaways
- Buy business-grade peripherals; consumer gear fails fast
- Wired beats Bluetooth on fixed counters
- Digital receipts reduce disputes and paper cost
