  • Data converting apparatus and method, printing apparatus and method, printing controlling apparatus and method, printing system and method, and data transmitting method for converting print data
    Patent number: 7024500
    Abstract: In a printing system in which with a plurality of different types of controllers connected to one serial bus, different types of print data can be inputted to and printed by a printing unit. When a set top box and desktop and portable personal computers, different in type from each other, are connected to a IEEE 1394 serial bus, screen data is outputted from the set top box to an AV/C printer and PDL data is outputted from the personal computers to the AV/C printer. The AV/C printer judges the image type of the input data. Based on the image type, the printing system converts the print data to a type of print data supported by the AV/C printer.

  • Data converting apparatus and method, printing apparatus and method, printing controlling apparatus and method, printing system and method, and data transmitting method
    Publication number: 20020059482
    Abstract: In a printing system in which with a plurality of different types of controllers connected to one serial bus, even different types of print data can be inputted to and printed by a printing unit. When a STB 2, desktop PC 3 and portable PC 4, different in type from each other, are connected to the IEEE 1394 serial bus 1 A, screen data is outputted from the STB 2 to an AV/C printer 5 and PDL data is outputted from the desktop PC 3 to the AV/C printer 5, the type of the input data is judged by the AV/C printer 5. Even a PDL data not supported by the AV/C printer 5 can be printed by converting it to PDL data interpretable by the AV/C printer 5.
