Abstract
Ethernet and Universal Serial Bus (USB) powered printing devices are provided. In particular, Ethernet and USB powered printers and methods of Ethernet powering of printers that support high speed printing and/or data intensive printing. Such high-speed and/or data intensive printing operations are able to be Ethernet or USB powered by providing for a power storage unit within the printer device that is able be charged during non-printing periods and provide for necessary energy bursts to support such higher powered processes. In addition, the present invention provides for devices and methods that allow for printers to operate with main power provided by conventional power mains and for back-up or secondary power to be supplied by Ethernet or USB power. Additionally, the invention provides for Ethernet or USB powering, both primary and back-up, of the data and configuration settings in the printer control and image generating electronics. In the back-up power mode, the Ethernet or USB power insures that data and configurations are not lost during periods of main power outage. The invention also provides a printer and method that can optimize a printing operation, e.g., by adjustin…
