  • Patent number: 6631900
    Abstract: An apparatus that can rotate a sheet 180° or invert the sheet, if required, includes a horizontal cylinder. The apparatus includes a horizontal cylinder. A front image output sheet wraps around the horizontal cylinder (turning counter-clockwise), entering the cylinder from the bottom. The cylinder then rotates 180° with the wrapped sheet. Continued counter-clockwise rotation of the cylinder will now unwrap the sheet from the cylinder and drive it away from the cylinder. In order to accomplish inversion, a deflector is raised in front of the cylinder. A sheet is directed over the top of the cylinder by the deflector as the cylinder turns clockwise. The sheet wraps around the cylinder and thereafter, the cylinder is rotated counter-clockwise resulting in the sheet exiting the cylinder at the bottom after having been inverted.

  • Publication number: 20030038958
    Abstract: In a digital printing system, such as including one or more printers connected to a host computer via a network, it is occasionally desired to download software for new fonts to the printers. In many cases, different printers support different “font types” or “font formats,” meaning different encoding methods for the font software. The various printers on the network are queried by remotely querying the MIB associated with each printer, to determine what font type is supported by each printer. When the font software is downloaded, where necessary for a particular printer, the original font software is converted to be supportable by the printer.
