Patent number: 7139908Abstract: An information processing apparatus comprising a power unit, a first control unit and a second control unit in which power supply is controlled based on a control signal from the first control unit, wherein when electric power supply from the power supply unit has been stopped and then the electric power supply from the power supply unit has been started, if update of a memory of the first control unit has been instructed, the first control unit transfers the content of a flash ROM in the first control unit into the memory thus updates the content of the memory. At this time, the second control unit is kept in a power-off status by a control signal line until the update of the memory is completed. After the completion of the update, power-on is notified by the control signal line, and the reset status of the second control unit is released.Type: GrantFiled: May 12, 2003Date of Patent: November 21, 2006Assignee: Canon Kabushiki KaishaInventors: Akihiko Hamamoto, Tetsuya Kawanabe, Takao Aichi, Kazuyuki Masumoto, Fumihiro Goto, Makoto Hibi, Tetsuya Suwa, Mitsuhiro Ono, Masato Oshima

Patent number: 6594028Abstract: A printer driver executable in a computer connectable to a driven printer. In response to initiation of a print job, the print driver obtains current status of the printer. Based on the status of the printer, the print driver modifies operational parameters of the printer prior to commencement of the print job, so that the operational parameters are different from default ones of such parameters. In addition, the print driver modifies its own operational sequence based on the printer status, so that the operational sequence of the printer is different from a default sequence without such status information.Type: GrantFiled: April 14, 1999Date of Patent: July 15, 2003Assignee: Canon Kabushiki KaishaInventors: Akihiko Hamamoto, Peter L.
