Product Features
Technical Overview
The LQ-780 employs impact dot matrix printing technology with a 24-pin print head that strikes an inked ribbon against paper to create characters and graphics. This mechanical approach enables the printer to produce up to six simultaneous copies using multipart forms, making it ideal for invoices, receipts, shipping documents, and other business forms requiring carbon or carbonless copies.
Print control is managed through Epson ESC/P2 and IBM 2390 Plus language emulations, providing compatibility with a wide range of business applications and legacy systems. The printer includes 13 standard character sets, 15 international character sets, and 8 barcode formats for flexible document creation. With a Mean Time Between Failures (MTBF) rating of 20,000 hours, the LQ-780 is built for continuous operation in demanding office environments.
