Kassatulostin Epson TM-U220IIB sarjaportti PS NE anturi ECW

The Epson TM-U220IIB Serial PS NE Sensor ECW is a serial-interface receipt and journal printer intended for point-of-sale environments. Designed for retail and hospitality counters, this compact ECW model supports reliable thermal printing via a Serial (RS-232) connection and incorporates both paper end and near-end (NE) sensors to alert when media is low or finished. The printer is built for continuous operation in busy service areas where space is limited and consistent print output is required.

Advantages

The design combines a small footprint with a durable mechanism that handles receipt and journal printing for prolonged use. Integrated paper end and near-end sensors reduce downtime by indicating media status before a run-out occurs. Serial (RS-232) connectivity ensures compatibility with a wide range of legacy POS systems and peripherals. The ECW form factor facilitates neat installation into counters or under-shelf mounts, helping maintain tidy service areas.

Suitable for

• Retail point-of-sale terminals where space is limited
• Restaurants and cafes for order and payment receipts
• Service desks and ticketing stations requiring reliable journal printing
• Legacy POS systems that use Serial (RS-232) connections

Key specifications

• Interface: Serial (RS-232)
• Media type: Receipt and journal paper rolls

How to use

Install the Epson TM-U220IIB on or under the counter in a location that allows easy access for paper replacement and cable routing. Connect the printer to the POS terminal using the Serial (RS-232) port and configure communication settings (baud rate, parity, data bits, stop bits) to match the host system. Load the receipt or journal paper roll according to the printer’s paper path instructions, then test-print a sample receipt to verify alignment and communication. Monitor the paper end and near-end sensors during operation to avoid unexpected interruptions.

Recommendations

Use quality thermal or compatible receipt paper specified for impact-style receipt/journal printers and keep the paper path free of debris to ensure consistent print quality and to prolong the life of the mechanism. Regularly check sensor operation and perform periodic maintenance such as cleaning the print head and feed rollers according to Epson maintenance guidelines.
