Direct thermal receipt printer for high-volume

The Citizen CT-S4000UBU-BK prints at up to 150 mm per second using line thermal dot technology at 203 dpi. It supports variable paper widths of 80, 82.5 and 112 mm with a maximum thickness of .150 mm. An integrated power supply reduces cable clutter on the workstation. A built-in buzzer provides audible alerts for paper end or error conditions.

Check USB port availability

The printer connects via a single USB interface and requires a Windows driver supplied on the included media. Verify that your point-of-sale system has an open USB port and can install the provided driver. The unit operates on AC 100-240 V input through the internal adapter, so no external power brick is needed. Ensure the operating environment stays between 5° C and 45° C with 10-90 % RH non-condensing.

Sustained printing handled by expanded roll

Larger paper rolls mean fewer interruptions during long print runs such as daily reports or prescription batches. Direct Memory Access moves text and graphics to the buffer quickly, keeping the 112 mm/sec engine fed during continuous operation. The auto-cutter and drop-in loading maintain throughput without manual intervention. Horizontal, vertical or wall-mounted positioning lets the printer fit the workflow without overheating in confined spaces.

Questions about this item

What comes in the box and what must be purchased separately?

The package includes the CT-S4000 printer, software media with utility and Windows driver, and an integrated AC adapter (100–240 V input, 24 V 2 A output). Thermal paper rolls in 80, 82.5 or 112 mm widths are not included.

Which paper width should I choose for my application?

The printer accepts variable widths of 80 mm, 82.5 mm and 112 mm. Select the width that matches your existing roll stock or the document format you need to print.

How fast will receipts actually print at the rated 112 mm/sec?

At the maximum 112 mm/sec speed, a typical 80 mm receipt prints in under a second; the built-in auto-cutter and top-exit path keep throughput high for continuous retail use.
