1. Paper drop-in mechanism; when supplying or replacing paper rolls, all you have to do is just
drop a paper roll into the printer and close its cover. This will facilita t e paper handling and
head cleaning greatly.
2. High speed (100 mm/s), and low-noise thermal printing.
3. Front-side paper ejection method, which allows the printer to be installed and used anyw here
with few restrictions.
4. Hermetic covering structure, which helps prevent any foreign matter or liquid from getting
into the printer.
5. Built-in input buffer.
6. Bar-code printing (Possible using special commands).
7. Page mode, which allows you to lay out pages freely.
8. Registration of user-def ined characters and logos into flash mem o ry.
9. Built-in Drawer Kick-Out interface.
10. Auto cutter mechanism provided as a standard unit.
11. Selection possible, as required, from two types: Easy-to-handle, built-in power supply type,
and lightweight f lat AC adapter type.
12. Use of 58 mm wide paper rolls possible by using the partition supplied.
