Produce value-added receipts and vouchers with 8 dots/mm (203 dpi) at 150 mm per second: the integrated cutter separates the receipts cleanly and automatically, and with special paper, the CT-S4000 also prints two-coloured receipts for promotions and advertising. An integrated flash memory module (384 kB) allows for storage of individual logos and symbols. The whole printing process is accelerated while waiting times are reduced significantly.

A sophisticated design makes it possible to place the CT-S4000 horizontally, vertically or using the optional wall-mounting kit, directly on the wall. The AC adaptor is already integrated into the compact body, which makes additional external devices obsolete. The integrated dual interface guarantees easy connectivity: every standard CT-S4000 model is equipped with a USB interface. Additionally, you can equip the printer with an optional parallel or serial interface to access existing infrastructure. Cash drawers are connected using one of the two printer ports.

The CT-S4000 is also available as a label printer variant for special applications. The CT-S4000L has the same specifications as the receipt printer model. It prints labels of various sizes and a maximum width of 112 mm using direct thermal printing at speeds of up to 150 mm per second. The integrated label sensor detects the end of every label flawlessly. Optionally, the CT-S4000L is also available with a reflective mark sensor (black mark) for labels without a liner and for perforated labels.

Like all other Citizen printers, the CT-S4000 also comes with professional customisation software. The configuration interface is extremely easy to use and allows extensive changes for one or many printers in just a matter of seconds.
