Hardware

Works with the hardware you already have

We don't force you to buy special or custom hardware like others do. Any Windows PC, any thermal printer with a driver, any cash drawer, any USB barcode scanner — keep what you have, or buy what suits you from us or from anywhere. If it's sold in Egypt, it almost certainly works.

PosMasr running on a touch till, a laptop and a kitchen screen

The computer

Windows 7, 8, 10 or 11 — 32 or 64 bit
Light: runs fine on older, cheaper PCs
Mouse, keyboard, or a touch screen
No internet connection required

Receipt printer

Since 5.1 the installer sets up the common USB receipt printers by itself — which ones; any other thermal printer with a Windows driver works too
58 mm or 80 mm paper (also 57 / 76 mm)
USB, LAN or Bluetooth — whatever the driver supports
Common brands: Xprinter, Epson, Bixolon, Rongta, Gprinter and the like

Cash drawer

Connected to the printer's RJ11 drawer port (the usual setup)
Or to the PC through a USB/serial (COM) trigger
Kick commands: ESC p, DLE DC4, BEL or custom bytes
One-button diagnostic finds the command that works

Barcode scanner

Any USB scanner that types like a keyboard (all the common ones)
Wired or wireless, handheld or desktop
Reads EAN-13, Code 128 and the labels PosMasr prints
Card reader (3.1): any USB magnetic-stripe or RFID/NFC reader in keyboard mode (≈300–900 EGP) — manager cards approve voids, returns and discounts, and any account can log in with its card
Weighing scale (3.2): any scale with an RS-232 / USB-serial port — CAS (PD-II, ER, AP), DIGI DS, Mettler Toledo and the Chinese price-computing scales (Rongta and the like); tap a by-weight product and the weight goes straight into the cart. Scale-label barcodes (EAN-13) still work as well

Label printer (optional)

Any label printer with a Windows driver (Xprinter, Zebra, TSC…)
Or print labels on the receipt printer itself
3-across rolls, pharmacy split labels, and standard sizes

Kitchen screen (optional)

A second monitor on the till PC, or
Any Windows PC/tablet on the same Wi-Fi or LAN
Connects to the till by IP — no server, no cloud
Or a second thermal printer in the kitchen: every order with items to prepare prints a ticket (2.2)

Customer screen (optional, 2.1)

Any second monitor on the till PC: HDMI, VGA or a USB display adapter
Windows display mode set to Extend (not Duplicate)
Shows the order, the total, the amount paid and the change to the customer
Or a small pole display (3.1): any 2-line VFD/LCD (2×20, EPSON / AEDEX / plain text) or 8-digit LED amount display on a COM or USB port — numbers and totals; Arabic names show as the barcode

Set up in minutes, tested from inside the program

Settings → Printer: pick your printer and paper width. Settings → Cash drawer: pick how it's connected. Then use the Tests tab: test print, test drawer, detect the drawer port, and preview the receipt at real size — before you enable printing on every sale.
