Complete Your Register Setup

A cash register usually needs supplies and accessories to work the way your business operates. Before ordering, confirm the register model, printer type, cable requirements, and any optional devices you want to connect.

• Shop 58mm thermal paper for the built-in SAM4s ECR receipt printer. The SAM4s ECR models in this listing use 58mm receipt paper.
• Shop 80mm thermal paper for compatible external POS receipt printers. Use 80mm paper only when your added printer requires 80mm media.
• Read the receipt paper guide if you are not sure which roll width, roll diameter, or paper type you need.

What the Options Mean

• Raised keyboard: Traditional physical keys for retail, liquor stores, convenience stores, gift shops, produce, specialty foods, and department-based checkout.
• Flat spill-resistant keyboard: Wipeable menu-style keyboard for restaurants, bars, cafes, delis, bakeries, pizza shops, quick service, and other food service counters.
• Single printer with no journal printer: A compact printer setup for customer receipts with electronic journal features where supported.
• Receipt and journal printer: A dual-printer setup for businesses that want a customer receipt and a separate paper journal station.
• Ethernet port: Helps with network-based setup, communications, polling, and supported connected workflows.

Optional Add-Ons and Peripherals

Supported SAM4s models can be built into a more complete checkout station with the right peripherals, cables, and programming. Compatibility depends on the exact model and configuration.

• Barcode scanners can speed up checkout and reduce manual price entry for UPC items.
• Kitchen printers can be added for restaurants, bars, cafes, delis, pizza shops, and prep areas when the register model and interface support remote printing.
• Cash drawers and second drawer options may be available for certain SAM4s installations.
• Pole displays can show item and price information to the customer at checkout.
• Scale integration may be useful for produce, deli, meat, candy, specialty food, and other weighed-item sales when supported by the register model and local legal-for-trade requirements.
• Integrated payment may be available on select configurations with compatible payment hardware, processor support, and setup.

Important: scanners, scales, kitchen printers, pole displays, integrated payment, and second cash drawer setups may require model-specific cables, interface settings, programming, and setup support. Contact Spartan POS if you want us to confirm the right accessory package before you order.

Need More Than a Cash Register?

A SAM4s cash register is a good choice for simple checkout, dependable receipt printing, tax rates, departments, PLUs, clerk totals, and basic reporting. If you need more advanced features such as detailed inventory, customer accounts, loyalty, online ordering, multi-store reporting, employee permissions, advanced promotions, accounting integrations, or ecommerce integration, a full POS system may be a better fit.

Use this quick comparison to choose the best SAM4s cash register for your store. Built-in SAM4s ECR printers use 58mm thermal receipt paper. Use 80mm thermal paper only when adding an external receipt printer or kitchen printer that requires 80mm rolls.

What the Main Options Mean
