Straight answers about the hardware we build: terminals, printers, kiosks and the peripherals around them. Sizes, interfaces, dot counts and voltages are the figures printed on the product pages, not marketing ranges. If a question about your site is not here, send the workstation and we will answer it with a model number.
All-in-one terminals from 11.6 to 15.6 inch — Windows range for legacy POS software, Android range for cloud apps.
The operating system decides which software you can run, not the hardware around it. The Windows terminals use an Intel J1900, J3455 or J4125 board up to Core i5, with 4 to 16 GB DDR4 and an mSATA or M.2 SSD, which is what legacy POS suites, scale drivers and local databases expect. The Android terminals use an RK3566 or RK3568 Cortex-A55 board with 2 to 4 GB RAM and 16 to 32 GB eMMC — enough for one cloud POS app, and cheaper per till.
15.6 inch at 16:9 gives the widest item grid and suits touch-first POS apps. 15 inch at 1024×768 is 4:3, which matches older Windows software written for that aspect ratio, so nothing is letterboxed or stretched. 11 inch (DCA-NB11) or 11.6 inch (DCA-POS116A) is for counters under about 500 mm deep, where a 15 inch head would block the customer's view of the drawer.
Yes. The 15 inch bodies take a 9.7 or 12 inch second display, with capacitive touch as an option, or a 2×20 VFD or LCD panel mounted on the back cover for order totals only. Both screens run from the same unit — no second PC, no second power supply.
The typical configuration is 6 external USB, 2× RS-232 COM, 1× RJ45 LAN, 1× RJ11 for the cash drawer and 1× Line Out plus Mic In, all fed from a single 12 V/5 A adapter. That covers receipt printer, scanner, drawer and scale without a hub. Port layout can be changed on an OEM run.
The Celeron J1900, J3455 and J4125 configurations are fanless, so there is no intake pulling flour, dust or grease into the chassis. Core i3 and i5 configurations ship with a CPU fan because the thermal budget needs it. If the unit lives in a bakery or next to a fry station, take the fanless board.
32 GB mSATA is enough for Windows, the POS application and months of local transaction logs; go to 128 GB or more if you cache product images or run a local database. Storage is mSATA or M.2 up to 512 GB, with an optional 2.5 inch SATA bay for a larger SSD or HDD.
Windows 7, 10 and 11, POSReady, WEPOS and Linux on the Windows line; Android 11 or newer on the Android line. The image is flashed and burned in at the factory, so the unit arrives with your build and your boot logo instead of a retail OS you have to strip and reimage.
All three are 15 inch Windows terminals on the same board family. The DCA-151WS is the fixed 4:3 1024×768 model, the 152W uses a foldable stand so the head folds flat for shipping and low counters, and the 155W takes either a 15 or 15.6 inch panel at 1024×768 or 1366×768.
Yes, and most multi-site rollouts end up doing it: Windows at the back office and service counter where legacy software rules, Android at pop-up and satellite tills. Mounting, drawer port and printer interface are the same, so peripherals move between them. Only the software stack differs.
All-in-one when the counter is fixed and the unit has to look like furniture: one power cable, one enclosure, drawer and serial ports built in — see what an all-in-one POS system is. Mini PC when the display is a different size or the PC has to hide in a cabinet; the industrial mini PC M100 is fanless, has 2× Gigabit Ethernet and runs from -20 to 60 °C.
Pistol-grip and PDA terminals for line busting, shelf audits and receiving — handheld range.
Three jobs, mostly: line busting at peak, shelf price and stock checks, and receiving. The terminal pays in the aisle, so the queue at the counter stays short. A model with a built-in printer, like the DCA-H61, also hands the receipt over where the customer stands. Start from what a POS system is if you are new to the category.
The DCA-H61 carries a 58 mm thermal printer in the grip: 50 mm/s, a maximum roll diameter of 42 mm and a print head rated for 50 km of paper. The other handhelds print to a belt printer over Bluetooth instead, which keeps the terminal lighter and leaves room for a bigger paper roll.
The H61 pack is 7.4 V / 5000 mAh and field-replaceable. Real shift length depends on printing duty rather than scanning: on a busy floor the paper roll and the 50 km head rating run out before the battery does, so carry spare rolls before you carry a spare pack.
1D CCD covers retail EAN and UPC labels and costs less. A 2D imager also reads QR, DataMatrix and PDF417, and keeps working on a scuffed or partly covered 1D label — which is why it is the default for receiving, pharmacy and asset tagging. See what a barcode scanner reads for the difference in symbologies.
Both, on the models built for it: the H61 covers GSM, WCDMA, FDD-LTE and TDD-LTE with regional band variants, plus 802.11 b/g/n and Bluetooth 4.0. Coverage inside a steel-shelved store is usually the binding constraint, not the radio, so check access point density before blaming the terminal.
Not from the built-in printer: that mechanism is receipt paper only, with no gap or black-mark sensor. For shelf labels and price tags pair the handheld with a 58 or 80 mm mobile label printer, which adds the sensor and the label liner path.
We do not publish an IP rating for the handheld line, so treat them as indoor retail devices. If your site washes equipment down or works in a cold store, say so at enquiry stage and we will either spec a sealed variant or point you to a different model rather than let the fleet fail in the field.
The H61 runs Android 8.1 or 11 and the H20 runs Android 10, both standard builds with the scanner exposed as a keyboard wedge or through an intent, so most Android POS apps install unchanged. A custom ROM, a pre-installed MDM agent or a locked-down launcher is an OEM/ODM scope.
80 mm and 58 mm receipt printers plus direct thermal label printers — printer range.
80 mm prints across 72 mm at 576 dots per line, which fits about 48 characters of the standard 12×24 font — enough for item, quantity, price and modifier on one line. 58 mm prints 48 mm at 384 dots and 32 characters, so lines wrap; it is the right choice for handhelds, delivery bags and tight counters. The POS-8250 is our reference 80 mm model.
203 dpi is 8 dots per millimetre, so a 72 mm print width is 576 dots and a 104 mm label width is 800 dots. At that density text is crisp at normal reading distance. Go to 300 dpi only when you print dense 2D codes or small multi-line label fields that would smear at 203 dpi.
The 80 mm line runs at 220 or 260 mm/s depending on model and setting, against 70 to 90 mm/s for a 58 mm printer. Speed drops on dense graphics and heavy bold text, and it also depends on the 24 V/2.5 A supply holding voltage — a long thin extension cable will cost you throughput.
A full cut separates the receipt; a partial cut leaves a tab so the slip stays attached, which is what kitchen tickets want. The 80 mm models ship with full or partial cut. The 58 mm POS-5890U has no cutter, which is fine behind a handheld-style counter but not for a queue.
Ethernet. USB ties the printer to one PC and to that cable run, and Bluetooth drops when the pass gets busy with other radios. A LAN printer can be addressed by IP from the POS, the kitchen display and a second till at once, and it survives a PC swap without re-cabling.
The drawer solenoid and the printer's drawer port must agree on voltage. Most of our 80 mm printers output 12 V/1 A on the RJ11 drawer port, while a 24 V solenoid drawer needs a 24 V port or a drawer whose solenoid is specified at 12 V when you order. It is the most common peripheral mismatch we see.
An 80 mm printer takes a 79.5 ±0.5 mm roll with a maximum diameter of 83 mm (80 mm on the shorter 8360 body) and 0.06 to 0.08 mm thickness; a 58 mm printer takes a 58 mm roll up to about 50 mm in diameter. Thicker or oversized rolls bind against the head and shorten its life.
The 80 mm heads are rated for 100 km of paper and the 58 mm heads for 50 km. At 80 m per standard 80 mm roll that is roughly 1,250 rolls per head, so a till changing a roll a day gets about three years — provided the paper is coated on the print side and the head is cleaned with isopropyl.
When the output has to stick to something. The label line prints at 160 mm/s and 203 dpi — 800 dots across a 104 mm effective width, on media up to 110 × 100 mm — with transmissive and reflective sensors for gap and black-mark labels, and speaks TSPL/CPCL as well as ESC/POS. The POS-9220 is the 4 inch example: 110 × 100 mm media, 104 mm effective print width.
Windows drivers from 2003 through 11, plus macOS and Linux, and ESC/POS or TSPL/CPCL command sets so an app can drive the printer without any driver at all. Android and iOS work over Bluetooth or LAN. We can supply sample code for the exact commands your app sends.
Usually the platen roller rather than the head: a worn roller stops pressing the paper evenly against the heating elements. Clean the head with isopropyl, confirm the paper is thermal-side out, and if the streaks survive a new roll, the head or platen is due for replacement — both are field-replaceable. Background on the mechanism is in what a thermal printer is.
21.5 to 32 inch wall-mount and freestanding ordering, check-in and queue kiosks — kiosk range.
Often the same enclosure with a different module stack. An ordering kiosk needs a payment terminal cutout, a receipt printer and a card reader; a check-in or queue kiosk needs a 1D/2D scan window and often no printer at all. Tell us the flow and we configure the cutouts to match. What a kiosk is covers the hardware envelope.
21.5 inch is the sweet spot for a counter-top or freestanding unit where the customer stands 400 to 600 mm away. 23.8 to 27 inch suits a wall-mounted unit read from about 800 mm back, and 32 inch is for menu-scale displays where the kiosk doubles as signage. All are 1920×1080 with 10-point projected capacitive touch.
Yes. The compact H and K bodies take an embedded 80 mm printer — 72 mm print width, 170 mm/s, partial cut — plus a 1D/2D scan window in the same enclosure. If you only need QR tickets, the printer can be dropped and the opening closed with a blank panel.
Wall-mount when floor space is the constraint: the A238, A238S, B and Q series hang on a bracket with adjustable height, and the target band is 90 to 130 cm from finished floor. Floor-standing when the unit has to sit in a lobby or an entrance without a suitable wall, as with the 21.5 inch R series. The DCA-A238 is the reference wall-mount unit.
An Intel J1900 up to Core i7 board with 4 to 16 GB DDR4 and a 64 to 256 GB SSD for Windows or Linux, or an RK3288/RK3399 Android board. If your app is a web view, the Android board is cheaper and fanless. If it needs Windows drivers for a payment terminal, take the Intel board.
The panels are 300 to 350 nits, which is right for indoor retail and hospitality lighting. They are not sunlight-readable: a kiosk facing a shop window or an open-air concourse needs a high-brightness panel and an anti-glare treatment, which is a different build. Raise it before the order, not after.
50,000 hours to half brightness, which is about 5.7 years of continuous 24/7 operation, or well over a decade at 12 hours a day. Because the panel rather than the PC sets the replacement cycle, plan the software and the mount around that horizon.
Colour, logo, silk-screen, boot logo, packaging and port or cutout positions are all open on a standard platform, and a new bezel or housing is an ODM scope. Powder-coat colour and enclosure geometry are the two changes that move MOQ most, so fix them early — the OEM/ODM service page explains where the line sits.
Wipe the glass with a non-ammonia cleaner, clear the printer path and paper dust weekly, and check the bracket fasteners and cable glands on the same visit. Keep the PC vents clear: a wall-mounted unit in a greasy environment pulls air across its own heat sink and needs that gap left open.
What hangs off a terminal or a printer: barcode scanners, cash drawers and customer displays.
1D reads the linear symbologies on retail packaging — EAN, UPC, Code 128 — and costs less. 2D reads those plus QR, DataMatrix, PDF417 and HanXin, and holds up better on damaged labels and on codes shown on a phone screen. Loyalty QR and digital wallets are what make 2D the safer default now.
Handheld for shelf work, receiving and anything you carry. Presentation, meaning omni-directional, for a checkout where the cashier presents the item and never aims. Desktop for pharmacy, lab and counter work where small codes dominate. The POS-1800A reads a 14 mil QR from 1 cm to about 20 cm, which is what lets an operator scan without looking.
It is the narrowest bar element the imager can resolve, so ≥4 mil covers retail labels comfortably. Depth of field matters more day to day: the usable range is roughly 1 to 20 cm on a 14 mil QR and 1 to 9 cm on a 7.5 mil PDF417, so a scanner with a wide window tolerates a careless operator.
Wired USB for fixed stations: no charging routine, no pairing to fail. Wireless when the scanner has to travel — stock counts, receiving bays, table-side ordering — and then budget the battery as a consumable with a replacement interval rather than waiting for a dead scanner at peak.
Match the solenoid to the port that drives it: 12 V or 24 V, specified at order. Our 80 mm printers commonly output 12 V/1 A on the RJ11 drawer port, so a 24 V drawer will not fire from it. Ordering the drawer with the solenoid your fleet already uses avoids the problem across mixed sites.
The POS-410A is 410 × 420 × 100 mm in cold-rolled steel with a ball-bearing slide, 4/5/6/8 bill compartments with metal wire grips and 8 adjustable coin slots. Interface options are RJ11, RJ12, USB, RS-232 or a DC jack, and a micro switch reports the open state back to the POS.
VFD for two lines of 20 characters — item total, change due — and nothing else: cheap, readable in low light, needs a serial port. An LCD, 7 inch or 10.1 inch IPS, shows item lines, promotions and a QR code, and is the better fit where the display also has to sell something.
No. A 9.7 or 12 inch second screen on the terminal already faces the customer and shows the same content. A pole display is for terminals with a single screen, or where the counter layout puts the customer off to one side of the till.
