The Epson LX-350 is a dot matrix printer with dot matrix technology, designed for use in office environments where continuous paper or carbon copy forms are required. The printer features a 9-pin print head and is designed for a maximum print width of 80 columns, making it suitable for standard and form printing. The print resolution is 240 x 144 DPI, with a maximum print speed of 357 characters per second – at a print density of 12 characters per inch in HighSpeed Draft mode. In Draft mode, the printer achieves 312 characters per second, while the NLQ mode (Near Letter Quality) offers a speed of 78 characters per second. Print direction is bidirectional, which increases print speed and improves print quality.

Applications

The Epson LX-350 is specifically designed for applications requiring carbon copy documents or continuous paper, such as in logistics, retail, or administration. The maximum number of copies is four carbon copies plus one original, making it suitable for generating invoices, orders, or shipping labels. Print size is limited to A4 (210 x 297 mm), with paper loaded manually. Supported media types include envelopes, roll paper, and sheet paper in single and multi-layer configurations.

Functions and Features in Detail

The printer includes an integrated 128 KB buffer, which accelerates data transfer and makes printing operations more efficient. The page description language is Epson ESC/P2, enabling compatible control of the printer. Integrated support for barcodes includes formats such as Code 128 (A/B/C), Code 39, EAN13, EAN8, Interleaved 2/5, POSTNET, UPC-A, and UPC-E, making it suitable for applications in inventory and logistics. The sound pressure level during operation is 53 dB, which is relatively quiet for a dot matrix printer.

Technology Explained Simply

The printing technology is based on a 9-pin print head, which applies individual dots to the paper via mechanical impulses. This technology enables the creation of text and simple graphics, with print quality influenced by resolution and print speed. The print head lifespan is 400 million characters, while the ribbon life is 4 million characters. These values highlight the high reliability and low consumption of the device. The mean time between failures (MTBF) is 10,000 hours, confirming the printer’s durability.

Compatibility and Accessories

The Epson LX-350 is equipped with parallel interface, USB 2.0, and serial interface (RS-232), enabling easy integration into existing systems. Compatibility includes operating systems Windows 2000, Windows XP, Windows Vista, Windows 7, and Windows 8. As consumables, a ribbon cartridge is required, which is included in the delivery. Optionally, a paper roll holder (part number C12C811141) is available, facilitating the use of roll paper.

Installation and Mounting

The printer is manually loaded with paper, with sheet paper, envelopes, or roll paper inserted from the rear. Paper output also occurs from the rear. The compact design with dimensions 348 mm (width) x 275 mm (depth) x 154 mm (height) and a weight of 4.1 kg allows placement on a desk. The integrated cable management system supports neat cabling.

Operational Advantages

The Epson LX-350 is characterised by energy efficiency: power consumption is 27 W during operation and only 1.1 W in standby mode. The device is ENERGY STAR certified, confirming its low energy consumption. The high ribbon yield of 4 million characters and the long print head lifespan reduce operating costs. The integrated software Epson Status Monitor enables monitoring of the printer’s status. The delivery includes the main unit, setup instructions, an instruction manual on CD, drivers and utilities, software, a power cable, and a ribbon cartridge.

Operating Conditions

The printer can be operated at temperatures from 5 to 35 °C and relative humidity from 10 to 80 %. Storage conditions match operating conditions. The device is designed for indoor use and requires no special environmental conditions.
