THERMAL LINE PRINTERS
Extremely fast, quiet output and exceptionally clear characters are just some of the advantages of thermal printers.
There's no need to change the ribbon because printing is performed directly onto the paper.
Paper loading is easy due to a simplified paper path.
And printing is possible on a wide range of media, including polypropylene and clear labels.
Outstanding Performance & Versatility
Prints everything from slips and receipts to journals. 
Ultra-fast output of up to 88 columns on A4-size paper 
with bi-directional, logic-seeking printing.
Reliability & Convenience
The reliability is there. Plus a wide range of handy 
features including automatic paper cutting 
and easy paper loading and ribbon changing.
Fast & Super Quiet
Throughput is fast thanks to bi-directional minimum 
distance printing. 
Quieter than other impact dot matrix printers of its class.
Handy Features
ASB (Automatic Status Back) function automatically 
transmits changes in printer status. 
Also offers the convenience of two-way paper loading.
