Citizen CT-S851IIIS3PAUBKP Thermal POS Ct-S800 Type III Front
Overview
The Citizen CT-S851IIIS3PAUBKP is a Type III front thermal printing module for the Ct-S800 series point-of-sale printer line. This unit provides integrated thermal printing capability with USB and parallel (PAR) connectivity options — suited for retail terminals, restaurant checkout systems, and warehouse label environments where you need fast, reliable receipt or label output without separate printer hardware.
Compatibility
Designed specifically for Citizen Ct-S800 Type III systems. Verify your existing POS printer base model before ordering — this module replaces or upgrades the front thermal assembly on compatible Ct-S800 Type III units. USB and parallel interfaces support legacy and modern POS terminals. Confirm your terminal's driver support for this module variant before deployment.
Installation Notes
This is a front-module swap — removal of the existing thermal head assembly is required. Ensure the Ct-S800 base unit is powered down during installation. After physical mounting, verify USB or parallel port connection is secure and test print output before returning the terminal to production. No special tools are typically required beyond standard thermal printer service procedures.
