LTP1245 PRINTER
The LTP1245 is a thermal line printer that offers
high-speed, high-resolution printing in a compact,
lightweight mechanism ideal for today’s 5V
portable applications. Providing low-power con-
sumption to support battery-powered operation,
the LTP1245 is a maintenance-free mechanism
and, with optional interface, allows for automatic
paper loading. Ideal for measuring instruments,
analyzers, POS, portable communications devices
and more, the LTP1245 maximizes printer func-
tionality in applications where minimizing power
consumption, size and weight is a priority.
•High resolution printing (8 dots/mm)
•High speed, low voltage printing (25mm @ 5V,
62.5mm @ 8.0V)
•Low 4.2V to 8.5V power supply operation
•Prints on label stock
•Available with or without paper feed knob
•Available with straight or curved paper path
(up to 95 µm)
•Thick paper printing possible on straight path
•Automatic paper loading (available with
IF1001-01B interface board)
•Wide opening head for easy access
•Wide temperature range

IF1001-01B INTERFACE BOARD
FOR LTP1245 SERIES
The IF1001-01B is an interface board used
specifically for the LTP1245 Series. It is
equipped with 8-bit parallel and serial TTL
data input terminals. The IF1001-01B brings
its printing functions into full play using a
wide variety of characters and function com-
mands.
PT100P01/PT101P01 AND PT120P01 CPU
FOR LTP1245 SERIES
