  • Printing apparatus and printing control method and character font pattern control method in printing apparatus
    Patent number: 7054018
    Abstract: Printing equipment for processing relevant print requests from a plurality of host devices in parallel and its printing control method. A plurality of logical printers are provided in one unit of physically existing printing apparatus and one logical printer is allotted to each one of host devices so that processing of the print data from a plurality of host devices can be carried out in parallel. One virtual host interface exists for each logical printer and this host interface establishes session with the corresponding host device to transfer data. Each logical printer independently takes charge of emulation, respectively. Operating a plurality of logical printers in one unit of printing apparatus realizes multi-session and multi-emulation.
