Printing apparatus, printing system and controlling method of printing apparatus

In a print system including a print server and a plurality of printers, when the occurrence of a failure in a first printer is detected, the print job to be processed first from among the print jobs accumulated in the first printer is identified as the first print job. Print jobs other than the first print job in the first printer are transferred to a second printer, and then deleted from the first printer.

Information processing apparatus, substitute print job management method, information processing program, and recording medium

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.

Proxy printing system, information processing apparatus, and controlling method

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.

Information processing apparatus, information processing method, program, and computer-readable storage medium

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.

Print control program and medium and information processing apparatus

A print control device that can communicate with a plurality of information processing apparatuses includes a managing section that manages scheduling requests for print jobs from the information processing apparatuses; and a control section that prevents reception of print data not based on scheduling requests if schedule requests are registered in the managing section.

Print controlling method and apparatus that prevents transmission of print data from clients until a predetermined time that is scheduled based on when the client registers with the managing section

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.

Print control program and information processing apparatus

To solve such a problem that it takes time to display a print setting display screen of a virtual printer to which functions of member printer drivers having different characteristics have been reflected, in an information processing apparatus for making job control of the virtual printer constructed by a plurality of member printers, a conflicting process based on each function of the plurality of member printers is executed, a construction of the member printers is examined in association with display control for reflecting a conflict result to a setting display screen of the virtual printer, and control is made to as to visualize an advance situation of the conflicting process on the basis of an examination result.

Information processing apparatus for controlling a print job using a virtual printer

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.

Information processing apparatus, information processing method, information processing program, and storage medium

An information processing apparatus and a pull print printing system are provided, which, according to a print instruction (print request, from a user, hold print data to be an object of printing, generate reference information for performing pull print corresponding to the held print data and utilize the generated reference information as reference information for requesting printing in order to causing an IPP printing apparatus to perform printing.

Information processing apparatus and print control apparatus, data processing method, storage medium and program

A print system is provided which is capable of selecting a client to which detailed print information is transmitted from among a plurality of clients when a user performs manual-feed printing in a network environment. In a network print system, for example, when a manual-feed-specified print is specified, a command for a manual-feed-specified print is added to the header part of print data of a print job. Then, when a server obtains an offline state of a printer, the server notifies the client of the offline status. The client receiving the notification displays a dialogue which notifies the user of the timing at which manual feeding is performed. It is also possible to provide an event request of a manual-feed timing to an application.

Print system, server, information processing apparatus, print control method, and recording medium

A client transmits only job information of print data to a server, the server manages a print order in accordance with the job information, and if printable, the client transmits the print data directly to a printer. After the print is completed, the printer notifies the server of a print completion, and upon reception of this print completion notice, the server instructs the client to delete the print data. In a print system on a network configured as above, the network traffic is not increased, a large memory capacity is not necessary for the server so that the server load is reduced, the job management of the server can be performed by the client, the completion of a print operation can be monitored, and a print operation is possible even if the server is in an error state.

Printing system that transmits job information independently of print

The conventional technology of designating a page with a scroll bar or by a dialogue and displaying the designated page can only display the designated page. According to the present invention, when an icon displayed in the form of a book in open state is designated with a mouse, the designated position is judged, and, if it is on the right-side page, the image of the designated page is displayed in compressed state to the designated point, and an underlying page is displayed. Then the designated page is turned over and the images of the succeeding two pages are displayed. When the left-side page is designated, the preceding two pages are displayed through a similar process.
