Sewoo SLK-TS400 POS Thermal Receipt Printer (With Lan)

The Double Fly / Sewoo SLK-TS400 POS Thermal Receipt Printer (With LAN) is an ultra-compact, front-loading commercial Point-of-Sale (POS) terminal engineered by the Korean manufacturer Sewoo. Unlike standard vertical-loading receipt printers, the SLK-TS400 features a highly specialized front-exit, cube-shaped architecture. This design protects the internal components from liquid spills, dust, and falling kitchen debris from above, making it an excellent choice for tight under-counter mounts, high-end retail desks, and demanding restaurant environments.

The defining operational feature of this specific model variant is its integrated RJ-45 Ethernet (LAN) connectivity interface. This network-capable setup allows the printer to bypass the strict physical length limits of standard USB cables. Instead, it can receive print data streams over an internal network infrastructure directly from remote tablet POS networks, cloud-based billing systems, or front-of-house waiter terminals. Built around an exceptionally reliable direct thermal print engine, the unit skips ink or ribbon replacements entirely, relying on a robust ceramic printhead array and a heavy-duty automatic guillotine blade to process receipts at high speeds.
