LTPH243 PRINTER
LTPH243 presents the first low power-supply
mechanism by Seiko Instruments supplemen-
ting the easy paper operation line. Using only
3V (voltage range from 2.7 to 5.6V) and due
to its comfortable battery drive of only one
lithium-ion or, alternatively, three Ni-MH /
Ni-Cd batteries, LTPH243 is an ideal print
mechanism for all portable devices such as
handheld terminals in the EFT-POS market.
The LTPH243 thermal printer combines extra-
ordinary compact design and high-speed, high
resolution thermal line dot printing with
easiest paper installation. A lock arm either
holds the platen or opens it when pushing the
release lever. In addition, two springs guaran-
tee an even pressure between thermal head
and platen roller. LTPH243 is applicable for
electronic cash registers, measuring instru-
ments and analysers, various POS applications
as well as communication and data terminal
devices.
High resolution printing (8 dots/mm)
High speed, low voltage printing
(30 mm/s @ 3.6V, 40.5mm/s @ 4.2V,
55.0 mm/s @ 5.6V)
Battery operation of 3 cells Ni-MH /
Ni-Cd batteries or 1 cell of lithium-ion
batteries for hand-held applications
Low 2.7 to 5.6V power supply operation
Improved operability of paper installation
and head cleaning by release lever
operation
Compact and lightweight (approx. 46g)
Low noise thermal line dot printing
Design to fit easily into the outer case
(reduced number of outer case parts)

INTERFACE BOARD & CPU
IFH301-01B INTERFACE BOARD
FOR LTPH243
The IFH301-01B is an interface board
designed for the LTPH243. It processes data
obtained from a host device, converts it and
transfers it to the LTPH243. The interface is
compatible with both parallel and serial
data input. It prints characters and bit
images as well as extended graphic charac-
ter sets. IFH301-01B also outputs internal
test patterns and gives information about
the status of the printer.
PTH30P01 CPU FOR LTPH243
Operating voltage of 3V to support
3.3V micro-controllers
Individual design-in for various
applications
Supports serial and parallel input
Less current printing by division control
according to the number of dots to be
activated
Reduction of current consumption and
motor heating by PWM control
Ensures high quality printing by auto-
matically adjusting the print density
according to temperature and voltage
Superimposing of character data and bit
image data
