Retail POS Hardware: Printers, Scanners & Cash Drawers
The right point-of-sale hardware makes a checkout fast, accurate and dependable — the wrong mix slows your line and frustrates staff. This guide walks through the full POS hardware stack, from the thermal receipt printer and cash drawer to the barcode scanner, customer display and tablet-based mPOS, and shows how to choose each piece by store type.

The Five Pieces of a POS Station
A point-of-sale station is a small system of parts that have to talk to each other. Get the combination right and a sale rings, prints and opens the drawer in one motion.
Receipt printer — the hub
The thermal receipt printer serves the customer's proof of purchase and, in most counters, doubles as the controller for the cash drawer. Because it sits at the center of the station, its interface and speed shape the whole checkout. Browse the Star Micronics receipt printer line for the workhorses of retail and hospitality.
Cash drawer & scanner
The cash drawer secures bills and coins and pops open on a printer signal, while the barcode scanner turns a UPC or EAN code into a line item in a fraction of a second. Together they are the difference between a smooth lane and a manual, error-prone one.
Terminal & customer display
The POS terminal — a fixed all-in-one or a tablet — runs the software that ties everything together. A customer-facing display shows the running total, builds trust at the counter and, in many markets, satisfies consumer-protection rules that require the buyer to see the price as it rings.
POS Receipt Printer Fundamentals
Nearly all modern receipt printers are direct thermal: they burn the image into heat-sensitive paper, so there is no ink, toner or ribbon to replace. The decisions that matter are paper width and how the printer connects to your POS.
Paper width. The two standards are 80mm and 58mm. An 80mm thermal receipt printer is the default for staffed retail counters and restaurants because it prints a wide, fast receipt with room for a logo, line items and a barcode. A 58mm printer takes narrow rolls and suits mobile, kiosk and lower-volume setups where footprint and paper cost lead the decision. Both are direct thermal, so consumable cost is just the paper roll.
Interface. The connection is what makes or breaks a tablet rollout. A traditional fixed terminal usually talks to the printer over USB or serial; a networked store puts the printer on Ethernet so several lanes and back-office systems can reach it; and a tablet or mPOS station pairs over Bluetooth, USB or, for iPad, Lightning. The Star Micronics receipt printer line is well known for offering the same model across these interfaces, which is why it is a frequent pick for cloud and tablet POS.
| POS setup | Typical printer interface | Why |
|---|---|---|
| Fixed PC terminal | USB or serial | One printer, one cabled terminal at the lane. |
| Multi-lane / networked store | Ethernet (LAN) | Shared access from several terminals and back office. |
| Tablet / iPad POS | Bluetooth, USB or Lightning | Wireless or direct pairing to a mobile device. |
| Mobile / pop-up (mPOS) | Bluetooth, 58mm portable | Battery power and a small footprint for the floor. |
Choosing the Cash Drawer
The cash drawer is the simplest part of the station and the easiest to get wrong. Two things decide the choice: how it is wired, and how it is laid out inside.
Printer-driven by design
In a standard counter the drawer does not plug into the computer at all. It connects to the receipt printer with an RJ11 or RJ12 cable, and the printer fires a kick signal that pops it open when a sale closes. That keeps the cabling simple and ties every drawer-open to the same audit trail as the receipt. Standalone USB and network drawers exist for tablet lanes without a fixed printer.
Size and till layout
Drawers come in compact and full-size footprints, and the till inside is configured for your currency — the count of bill slots and coin cups should match the denominations your cashiers actually handle. A boutique with a small counter and a grocery lane with high cash volume need very different drawers. See the range of Star Micronics cash drawers.
Build and security
A retail drawer is opened thousands of times a month, so a steel body, a smooth roller mechanism and a reliable lock matter for both durability and loss prevention. Media slots let staff drop large bills and checks below the till without opening the drawer, which is a small but real shrink control at busy counters.
Retail Barcode Scanners: 1D vs 2D
A scanner has two independent decisions behind it: which symbologies it can read, and how it is presented to the product. Match both to how your store actually rings sales.
| Scanner type | Reads | Best for |
|---|---|---|
| 1D laser | UPC / EAN and other linear barcodes | Lowest-cost lane for traditional product scanning |
| 2D imager | 1D plus QR & Data Matrix, incl. phone screens | Loyalty apps, mobile coupons, payment QR |
| Presentation (hands-free) | 1D or 2D, on a counter stand | High-throughput counters; staff sweep items past it |
| Handheld corded / cordless | 1D or 2D, trigger-based | Bulky items, shelf scanning, mobile floor staff |
The practical rule: if a customer will ever show a code on a phone — a loyalty pass, a coupon or a payment QR — you need a 2D imager, because a 1D laser cannot read a screen. For mixed retail and warehouse duty, Zebra's general-purpose scanners are a strong fit; the Zebra DS8108 2D imager is a popular high-performance handheld, and the broader Zebra scanner range covers presentation, cordless and rugged options.

Customer Displays, Shelf Labels & mPOS
Beyond the core three, two more pieces round out a retail operation: how you show and label prices, and how you take the checkout mobile.
Customer-facing display
A pole or tablet display that shows the running total as items ring builds trust at the counter and, in many Latin American markets, helps meet consumer-protection rules that require the buyer to see prices. It also speeds the line by letting customers spot a mis-scan before they pay.
Shelf & price labeling
Clean shelf edges and price tags depend on a label printer and label-design software. NiceLabel designs and standardizes shelf, price and promotional labels across a store or chain, and prints to thermal label printers — keep media on hand from the Zebra supplies catalog.
Tablet & mobile POS
A tablet running a cloud POS app becomes a full station with a Bluetooth or Lightning receipt printer, a wireless scanner and a printer-driven drawer. mPOS powers line-busting, pop-ups, markets and food trucks — and the Star Micronics printer line is a go-to for these builds thanks to its broad interface and SDK support.
How to Choose by Store Type
The same components combine differently depending on volume, mobility and what your customers scan. Use this as a starting checklist, then we will tune it to your floor.
| Store type | Printer | Scanner | Drawer / extras |
|---|---|---|---|
| Boutique / specialty | 80mm desktop or tablet 58mm | 2D handheld for loyalty & tags | Compact drawer; customer display |
| QSR / cafe | 80mm fast thermal + kitchen printer | 2D for app & QR ordering | Standard drawer; customer display |
| Grocery / minimarket | 80mm high-speed, networked lanes | Presentation hands-free + handheld | Full-size drawer; shelf labeling |
| Mobile / pop-up | 58mm Bluetooth portable | Bluetooth 2D or phone camera | Optional USB drawer; tablet POS |
There is no single right answer — the best stack is the one that matches your volume, your software and the way your customers pay. Tell us your store type and we will assemble a compatible bundle of printer, scanner and drawer, shipped across Latin America with USD quotes.
Frequently Asked Questions
What hardware do I need for a retail POS system?
A complete point-of-sale station is built from five components: a thermal receipt printer, a cash drawer, a barcode scanner, the POS terminal or tablet that runs the software, and usually a customer-facing display. Most stores start with a printer, scanner and cash drawer and add a customer display where local rules or queue speed call for it. The printer is the hub of the station because it usually drives the cash drawer and serves the receipt.
What is the difference between an 80mm and a 58mm receipt printer?
The numbers refer to paper width. An 80mm printer prints a wide receipt and is the standard for full-service retail and hospitality because it fits more line items, a logo and a barcode per row, and it prints fast. A 58mm printer uses narrow rolls and is common in mobile, kiosk and low-volume setups where the device footprint and paper cost matter more than receipt width. Both are direct thermal, so neither needs ink or a ribbon.
Do I need a 1D or 2D barcode scanner for my store?
A 1D laser scanner reads the standard UPC and EAN barcodes printed on most retail products and is the lowest-cost option for a traditional store. A 2D imager reads those same 1D barcodes plus QR and Data Matrix codes, which means it can scan loyalty apps, mobile coupons and payment codes shown on a customer's phone screen. If you accept any phone-based scanning, choose a 2D imager.
How does the cash drawer connect to the POS?
In most retail setups the cash drawer does not connect to the computer directly. It plugs into the receipt printer with an RJ11 or RJ12 cable, and the printer sends a kick signal that pops the drawer open when a sale is completed or a no-sale is rung. This printer-driven design keeps the wiring simple and ties the drawer to the same audit trail as the receipt. Standalone USB and network drawers also exist for tablet stations without a fixed printer.
Can I build a POS on a tablet or iPad?
Yes. A tablet or iPad running a cloud POS app is a full mPOS station when paired with the right peripherals: a receipt printer that supports the tablet over Bluetooth, USB or Lightning, a Bluetooth or USB barcode scanner, and a printer-driven cash drawer. This setup powers pop-ups, line-busting, food trucks and boutiques, and the Star Micronics receipt printer line is widely used for tablet and mobile POS because of its broad interface and SDK support.
