POS & Cash Register Accessories

Accessories are bought against a specific piece of equipment, not against a category. A cable, display, power supply or till insert can look correct, plug in physically, and still be the wrong part. Before ordering, confirm the exact host model, the interface it actually drives, the cabling and any programming the host needs.

What this category covers

  • Cash drawer accessories: till inserts, replacement keys and under-counter mounting hardware. These are matched to a specific drawer model and, for keys, a specific lock code.
  • Cables: printer, scanner and cash-drawer cables. Both ends have to match the ports, and a drawer cable also has to match the pinout the host drives.
  • Pole and customer displays: customer-facing displays generally require a specific port, a specific protocol and host-side programming.
  • Power supplies: matched to the exact device being powered, including the connector and the mains input available at the site.

Why we do not sell accessories as universal

Identical-looking connectors are used for different purposes across manufacturers. An RJ-style jack can carry a drawer kick signal on one device and something else on another; a USB port does not tell you whether the host supports the device behind it; and a scanner or display often has to be programmed on both sides before it works. This is why an accessory listed here is not described as compatible with a particular register unless that has been verified.

How to identify the right part

  1. Find the exact model of the equipment the accessory connects to.
  2. Note the port or connector it will use, and what is on the other end.
  3. For a drawer, note whether the register or the receipt printer opens it today.
  4. For a key or till insert, note the drawer model and the code stamped on the existing key or lock.
  5. For a power supply, note the voltage marking on the device and the original supply if you still have it.

Send us the model and we will identify the part

If you know the part number, we can confirm it. If you only know the equipment, that is usually enough for us to work backwards. Send us the model details or call (855) 867-2647. Support hours are 9:00 AM–5:00 PM Eastern.

Where can I buy cash register accessories and supplies?

SAM4sDirect carries cash-register and POS accessories for checkout systems across brands. Start with the exact register, POS, printer, drawer or peripheral model you already have, then match the accessory to that equipment rather than shopping only by connector shape.

Accessory What it does What to verify Start here
Barcode scanners Reads UPC/barcode item numbers into a compatible register or POS USB vs serial, cable, scanner protocol and register programming Barcode scanners
Receipt printers Adds or replaces external receipt printing Interface, emulation, paper width and cash-drawer port requirements Receipt printers

How to buy POS and cash-register supplies without ordering the wrong part

Send the exact model number and, when possible, a photo of the device label and the port the accessory connects to. For keys, tills or drawers, include the drawer model and lock/key code. That gives us enough information to verify most parts before they ship.

Accessories by category

Parts that support the counter, grouped by what they are.

Cables, displays, power supplies, till inserts and drawer hardware are bought against a specific piece of equipment. A matching connector is not proof of fit, so confirm the exact host model, interface and cabling before ordering.

Have us confirm the part

Need a cable, display, till insert or power supply?

Send us the exact register, printer, drawer or peripheral model and we will confirm the correct part before you order. We only recommend accessories after the part number, interface and fit have been verified.

If you already know the part you need, or you know the equipment and not the part, send us the model and we will identify it.

Compatibility depends on the exact host equipment, interface, cable, firmware and programming. Being listed on this page does not mean an item is compatible with a particular SAM4S register or printer. We verify the correct configuration before recommending or shipping a part.

Accessories & peripherals

Everything that connects to the register.

Each category below is bought the same way: identify the exact register or printer model first, then match the interface. We do not sell peripherals on the assumption that a connector fits.

Check compatibility first
Receipt printers Thermal printers for the customer receipt. Confirm USB, serial or Ethernet against what is actually driving the printer. Receipt printers → Kitchen & impact printers A remote printer placed in the kitchen, usually impact so the receipt survives heat and steam. Not the same as a register's second built-in station, which is normally a journal. Covered on the receipt printer page. See impact options → Barcode scanners 1D and 2D scanning. The barcode type, the interface and any register-side programming all have to line up. Barcode scanners → Cash drawers Register-driven or printer-driven. Similar-looking RJ connectors can use different pinouts and kick voltages. Cash drawers → Receipt paper Thermal and impact paper are not interchangeable. Width alone is not enough — roll diameter and the print station matter too. Receipt paper → Cash register accessories Pole and customer displays, cables, power supplies, till inserts and drawer keys. Each of these is matched to a specific host device rather than to a category. You are here

Start with the register you own

Shop accessories by SAM4S register model.

Select the exact current register first. Its setup page uses our structured links for programming, supplies, protection and hardware, and hardware still has to pass the compatibility gate before it can be added directly.

Older or discontinued model?Use the replacement center first so we do not treat an old model as a current accessory platform.
