1. INTRODUCTION
The CBM-710, CBM-720, CBM-730 and CBM-750 are dot impact printers which can be utilized for a wide
range of applications, such as data communications terminals, ECR terminals and kitchen printers. High speed
performance is made possible by a bidirectional printing system and, since these printers are compact, lightweight
and equipped with an abundance of functions, they can be easily employed for a variety of different tasks.
The CBM-720 and CBM-750 have a built-in automatic cutter capable of performing a partial cut (three
connecting points remaining) or full cut (one connecting point remaining), which can be controlled through printer
command codes.
Before using your printer, please read this manual carefully to be certain you have an adequate understanding of
its operation.
