Fast and productive, the LQ-780 prints the original plus six copies and is capable of impressive speeds of 487 characters per second (10 cpi) when using printer-resident fonts. In a demanding and fast-paced work environment, a high ribbon capacity is crucial. With 10 million characters per ribbon, the LQ-780 offers one of the highest ribbon capacities in the flatbed market. This results in fewer ribbon changes, low operating costs, and overall cost efficiency. The MTBF (Mean Time Between Failures) value of 20,000 operating hours ensures long and smooth operation. The robust casing withstands high humidity and heat conditions, and the automatic adjustment of paper thickness makes operating the LQ-780 intuitive. This leads to increased productivity, less maintenance, and reduced downtime.
