Patent number: 7855794Abstract: In a proxy printing system, one print job is transmitted to a first one of printers connected over a network, and when a print failure occurs in the first printer, a second networked printer processes the print job to perform proxy printing. The system detects a failure of the first printer attempting to process the print job and issues a notification. In accordance with managed history information for the first printer, the proxy printing system detects whether a printer that has previously processed a print job as a proxy for the first printer exists out of the networked printers. The system issues a notification indicating at least one detected printer as a proxy destination candidate. The system performs control so that the printer is used to execute proxy print processing, and updates the history management table after the execution of the proxy print processing.Type: GrantFiled: December 1, 2004Date of Patent: December 21, 2010Assignee: Canon Kabushiki KaishaInventors: Koji Kikuchi, Noriyoshi Kurotsu, Masamichi Ohshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Kei Kitagata, Hiroyuki Kayama, Kenichi Shirai

Patent number: 7804608Abstract: There are provided an information processing apparatus and information processing method, which can implement a job or printer device monitoring scheme that allows the user to easily detect status of printing apparatus in advance. The status of a physical printer device corresponding to a predetermined logical printer, which is set as an object to be monitored, is monitored, and a result based on monitoring is displayed on a computer display as a resident display. For example, when the resident display is displayed as an icon on the task tray on the computer display, it does not disturb display of windows of other document creation applications. Also, the user need not purposely instruct to launch a monitor utility upon printing. Hence, a job or printer device monitoring scheme which is very convenient for the user can be implemented.Type: GrantFiled: July 20, 2004Date of Patent: September 28, 2010Assignee: Canon Kabushiki KaishaInventors: Kenichi Shirai, Noriyoshi Kurotsu, Masamichi Ohshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Koji Kikuchi, Kei Kitagata, Hiroyuki Kayama

Patent number: 7719703Abstract: A print control program executed by an information processing apparatus, which spools print data created and spooled via a print data creation module such as a printer driver again and concurrently performs the re-spooling and output of the print data to a resending destination or an alternate device. It is thereby possible to speed up a throughput of the output on alternation of printing or resending.Type: GrantFiled: February 11, 2004Date of Patent: May 18, 2010Assignee: Canon Kabushiki KaishaInventors: Noriyoshi Kurotsu, Masamichi Oshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Koji Kikuchi, Kei Kitagata, Hiroyuki Kayama, Kenichi Shirai

Patent number: 7538902Abstract: A print control program, which is executed by an information processing apparatus so as to transmit print data to an image-forming device and record an image, causes the information processing apparatus to re-spool as a second spool file print data that has already been spooled once as a first spool file by an operating system. A portion of the print data that is re-spooled as the second spool file is transmitted to the image-forming device during re-spooling. As result, spooling of the second spool file linked to the first spool file, and transmission to the image-forming device, is more efficient.Type: GrantFiled: February 10, 2004Date of Patent: May 26, 2009Assignee: Canon Kabushiki KaishaInventors: Noriyoshi Kurotsu, Masamichi Ohshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Koji Kikuchi, Kei Kitagata, Hiroyuki Kayama, Kenichi Shirai

Patent number: 7426046Abstract: A print job icon symbolically representing a print job and printer icons symbolically representing a plurality of printers are displayed on the screen of a display in an information processing apparatus. When a command to transfer the print job icon is issued, whether a requested print job can be transferred to any printer is easily determined. When the print job is selected, the information processing apparatus easily discriminates between a printer able to output the print job and a printer unable to output the print job.Type: GrantFiled: December 1, 2004Date of Patent: September 16, 2008Assignee: Canon Kabushiki KaishaInventors: Kenichi Shirai, Noriyoshi Kurotsu, Masamichi Ohshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Koji Kikuchi, Kei Kitagata, Hiroyuki Kayama

Publication number: 20070146778Abstract: In a print system communicable with an information processing apparatus and print apparatus, the information processing apparatus holds one or a plurality of print jobs in a readable form based on identification information common to a plurality of print jobs transmitted from the print apparatus. When the print apparatus issues a request accompanying identification information to the information processing apparatus, the information processing apparatus receives the issued request, and reads one or a plurality of print jobs on the basis of the identification information contained in the received request. Then, the information processing apparatus outputs the read print job to the print apparatus.Type: ApplicationFiled: December 14, 2006Publication date: June 28, 2007Inventors: Kei Kitagata, Shin Muto

Publication number: 20050141013Abstract: In a redirect-on-error print system of this invention, when an error notification is acquired, only printer drivers having the same function as that of the printer driver which has output the data to the printer with the print error are listed up from registered printer drivers, and the user is caused to select a redirect-on-error print destination from them so that any inappropriate print output can reliably be avoided. In the redirect-on-error print system, a print job is transmitted to one of a plurality of printers connected to a network. When a print error has occurred in the printer, processing is executed to cause another printer to execute redirect-on-error printing of the print job. In the redirect-on-error print system, the error in the printer which is processing the print job is detected, and the user is notified of it.Type: ApplicationFiled: December 1, 2004Publication date: June 30, 2005Applicant: CANON KABUSHIKI KAISHAInventors: Koji Kikuchi, Noriyoshi Kurotsu, Masamichi Ohshima, Hidekazu Morooka, Takashi Yagita, Koichiro Wanda, Kei Kitagata, Hiroyuki Kayama, Kenichi Shirai
