The Printer provides visual and audio indications of its activities by means of two green LEDs and a
buzzer. The visual and audio indications are used to indicate whether the printer runs out of paper
or when there is approximately 25% of the paper roll left or when the receipt is ready.

The Printer is a compact, ruggedized thermal printer suitable for the harsh environment of the gas
station. It uses thermal printer paper only (55 gr., 57 mm width, 101 mm diameter).
The Printer is connected to the OrPT via an RS-485 link. The Printer requires a 24 – 26 VDC power
supply input.
The Printer enclosure is designed to survive the harsh forecourt environment. It uses Spark Gaps
protection for the links and 1.5 KV isolation.
The printer includes two sensors for paper usage alerts:
• Low paper sensor - activated when there is approximately 25% of the paper
roll left
• End paper sensor - activated when printer paper runs out completely
The paper usage and receipt indications include a buzzer sound and LED indicators or the
combination of both.
