  • Printing system and method that uses a universal serial bus (USB) high-speed interrupt out pipe to transfer print data from the host computer to the printer
    Patent number: 7978357
    Abstract: In accordance with the invention, it has been determined that the bandwidth, guaranteed periodic delivery and error correction characteristics of a USB High-Speed Interrupt OUT pipe of the USB 2.0 standard enable the Interrupt OUT pipe to be used to transfer print data from the host computer to the printer. By using the Interrupt OUT pipe for this purpose, it is no longer necessary to store an entire rasterized page in the formatter memory of the printer before commencing printing of the page. Consequently, the size of the formatter memory device can be relatively small compared to the size of the formatter memory device that is currently used to store an entire rasterized page. Alternatively, the same size memory device as that currently used to store an entire rasterized page may be used to enable higher resolution pages to be printed.
