The MCP8850B is a compact and lightweight portable printer with an Infra-red interface compatible with HP IR format in a new elegant
enclosure.
Designed for maximum versatility, the MCP8850B is compatible with existing systems whilst allowing many upgrades in terms of printing
speed and functionality.
It is powered from alkaline batteries and has maintenance free operation, only available with thermal printers.
Many different modes of operation are possible, including numerous character sets, all selectable by software commands.
The MCP8850B is one of a family of thermal printers designed and manufactured in the UK by Martel. All units are built into robust ABS
housings, with a choice of colours. We would be pleased to discuss the possibility of customising any aspect of the printer to specific
requirements.

Charging range +10ºC to +45ºC
MTBF Approx. 10 million lines (20ºC, print ratio = 25%)
The transmit/receive requirements for
interfacing with the MCP8850B are
compatible with existing systems, however
higher transmission speeds and printing
speeds are possible due to the incorporation
of a large 6Kbyte buffer and a high speed
thermal fixed head printer mechanism.
Higher print speed can be achieved by
minimising the inter-frame delays in the
transmission software, previously required
when using a slower printer mechanism.
Maximum distance for reliable infra-red
communication between printer and host
equipment is 45cm (18in). The infra-red port
at the front of the printer should be pointed
directly at, and horizontal to, the port on the
host equipment and the beam should not be
obstructed.
