Designed with productivity in mind, the LQ-780 is an ultra-reliable dot matrix printer that offers an impressive ribbon yield. It is fast and compact with a robust build. Its modern design allows effortless integration into any work environment, be it an office or a warehouse.

Fast printing:
Print faster and more productively. The LQ-780 prints the original + six copies, and is capable of printing an impressive 487 cps (10 cpi) when using printer resident fonts.

High ribbon yield:
In a demanding and fast-moving work environment a high ribbon yield is essential, and with 10 million characters per ribbon, this marks the LQ-780 as a leading force in the flatbed market. It is also cost-effective, with long ribbon replacement cycles, low running costs and total cost of ownership.

Dependable:
Durable and built to last, users will be assured by the MTBF (mean time between failures) of 20,000 power on hours. The robust casing can stand up to high humid and heat conditions, and automatic paper thickness adjustment makes the LQ-780 intuitive to use. This results in greater productivity and less maintenance from down time - essential when producing large amounts of documents and data.
