Ultra-Reliable Flatbed Printing
As a successor model from LQ-680Pro, the LQ-780 offers a high-performance advantage that modern offices are sure to appreciate : speed and connections. Both models comes with Parallel and USB port as standard. 

Best-In-Class Speed
The LQ-780 offers a class-leading throughput and an amazing top speed of 487 cps (at 10 cpi in High-Speed Draft mode). What’s more, our new 24-pin Eco-Drive print head mechanism achieves this high level of productivity without running up your electric bill. And when a print job is finished, the improved auto power-saving function puts the printer in low-power sleep mode for even greater savings.

Unrivalled Ease-Of-Use
Built into Every Feature A 25% more compact flat-top housing makes the printer ideal for countertop and desktop use. The front sheet guide has also been redesigned – it now features a lower profile, a full-flat bottom and an L-shaped edge guide for smooth, easy front loading. When not in use, the front loading tray can be folded upwards into its storage position to further minimize desk space usage. In addition, improved front-in, front-out paper handling ensures that front-loaded cut-sheet paper and single-sheet, multi-part forms emerge right-side-up for instant legibility. 

Reliability and Versatility
LQ-780 series’ print head life and total print volume have been extended even beyond the level offered by the widely acclaimed Epson LQ-680Pro, and you can now get crisp, clear output on multi-part forms up to seven layers thick. Versatility is also excellent, with two-way paper handling that allows paper to be loaded from the front and rear.

Printer Status Monitoring and Settings
The LQ-780 series printer comes included with Epson Status Monitor 3 and Printer Setting Utility software that allows you monitor the status of the printer, alerts you of any printer error that occurs and provides troubleshooting instructions when needed. You can use Epson Status Monitor 3 to set monitoring preferences, monitor status of shared printers or make print adjustments directly from your PC. 

The Auto Platen gap adjustment
With new automatic platen gap adjustment function, the LQ-780 series can automatically adjust the platen gap according to the thickness of paper used. This feature allows the LQ-780 series to print with clean and consistent print results without the need for manual input or adjustments by the users.
