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)
