The Mettler Toledo RS-P42 printer, an essential tool for measurement traceability
The Mettler Toledo RS-P42 printer is a dot matrix printer specifically designed for use with the brand's scales with an RS232C interface. It stands out for its robustness, ease of use and compliance with international standards for data quality and traceability. Its printouts on standard paper are thermally stable, light-resistant and allow long-term storage of results, which is essential in quality systems such as GLP, GMP or ISO 9001.
The RS-P42 is particularly intuitive to use. Installation simply involves connecting the communication cable to the balance and the mains power supply. The power supply is universal (100–240 V AC, 50–60 Hz), allowing worldwide use without additional adapters. Thanks to an integrated DIP switch, the transmission parameters (baud rate) can be configured to ensure perfect compatibility with the balance used, including the correct display of special characters.
The core of the RS-P42 is its 5x9 dot matrix printing technology with 24 characters per line. This technology enables legible and stable printing at a rate of one line per second. The ink cartridge is replaceable, ensuring simple and economical maintenance. The paper roll, which is a standard size (58 mm x Ø 51 mm), is also easy to change, making the RS-P42 ideal for frequent and prolonged use.
The printer's main features include manual line feed, automatic printing of the stable weight value from the scale, and a self-test function that prints the character set. These features allow you to check that the printer is working properly and ensure the reliability of each printout.
Beyond its ease of use, the RS-P42 is also designed to last. Its casing is made from durable materials that are compatible with all standard cleaning products. It can be used in environments with varying ambient conditions (temperature from +5 to +40°C, relative humidity up to 80% at 31°C). The only requirement is that it must not be exposed to liquids or used in explosive atmospheres.
Mettler Toledo provides a complete set of accessories and consumables to ensure the maintenance and longevity of the device. This includes ribbons, paper rolls, country-specific power cables and replacement parts supplied exclusively by the authorised after-sales service.
Thanks to its accuracy, simplicity and compliance with quality standards, the RS-P42 printer is an essential tool for any professional who wants to guarantee the traceability, reliability and integrity of their measurements.
