The Citizen CT-E351 is a bond printer of the PRNT series, designed for use in retail, gastronomy, and other areas where reliable and fast output of receipts, invoices, or tickets is required. The printer operates using the thermal direct method, in which print information is directly transferred onto thermal-sensitive paper without the need for ink or toner cartridges. The front output enables convenient removal of printed media directly at the front of the device, which is particularly advantageous in confined workspaces or behind the cash register. The device is black in colour and features a robust construction suitable for daily use in commercial environments.

Applications

The CT-E351 is suitable for applications requiring fast and clear output of text documents, such as in point-of-sale environments, restaurants, petrol stations, or mobile service providers. The maximum print width of 76 mm and media width of up to 80 mm allow the use of standard roll paper, which is widely available in the industry. The maximum roll size of 83 mm diameter provides sufficient paper capacity for extended operating times without frequent refilling.

Functions and Equipment in Detail

The printer achieves a maximum print speed of 250 mm per second, ensuring efficient processing of orders. The resolution is 8 dots per millimetre (203 dpi), providing clear and legible print quality, especially for text and simple symbols. Support for the ESC/POS command set enables easy integration into existing systems based on this standard. The USB and RS232 interfaces offer flexible connection options to various host systems, such as cash registers, POS terminals, or computers.

Technology Explained Simply

The thermal direct method works by direct heat transfer onto thermal-sensitive paper. The paper is fed through a print roller that is heated at specific points to create the print dots. This technology is low-maintenance, as no ink cartridges or toner are required. Print quality is sufficient for text and numeric information, but not suitable for coloured graphics or high-resolution images. The print speed of 250 mm/s is appropriate for high-throughput environments, enabling fast output of receipts.

Compatibility and Accessories

The CT-E351 is equipped with USB and RS232 interfaces, enabling connection to a wide range of systems. Support for the ESC/POS command set ensures compatibility with many common cash register systems and software solutions. The use of standard roll paper with a width of up to 80 mm and a diameter of 83 mm is possible, ensuring high availability of replacement supplies.

Mounting and Installation

The printer is designed for use on a flat surface, such as a counter or desk. The front output allows direct removal of printed receipts. Installation is performed via the provided USB and RS232 interfaces. The included power supply unit and power cable (EU plug) enable easy power connection. Setup is done by configuring the interface in the host system, with ESC/POS compatibility simplifying integration.

Advantages in Operation

The CT-E351 offers a reliable and low-maintenance printing solution, as no ink or toner cartridges are required. The fast print speed and clear print quality ensure efficient workflow. The front output and compact design facilitate placement in the work area. Support for USB and RS232, as well as ESC/POS, ensures broad compatibility with existing systems. The included power supply unit and power cable (EU) reduce the need for additional purchases during commissioning.
