Compact Battery drivable thick film
thermal printhead (8dots / mm)
KA2003-BE10A


Compact and lightweight they are ideal print heads for handheld printers and PDAs (personal digital assistants).

Applications
Mobile printers
EFT-POS printers
Hand-held printers
Debit printers

Features
1) The B series brings reduced height of protective resin for IC and enlarged paper pathway for thermal papers. Thanks
to ROHM's latest LSI high integrated mounting technology and it's ultra slim 192bit driver IC.
2) The B series accede the great world class low energy consumption characteristics of GP series.
3) Because the print heads circuits draw 2.7V, the printer can be driven using a single lithium battery.
