There is disclosed an information processing apparatus which efficiently and effectively executes printing even when interruption of printing occurs in a printing apparatus. The apparatus which includes a plurality of print queues each functioning as one of a backup print queue and a basic print queue and executes output to a printing apparatus based on print job information with higher priority than output to a printing apparatus based on backup job information, comprising, output means for outputting a print job in accordance with schedule up of one of pieces of print job information and backup job information registered in the plurality of print queues, and registration means for, in accordance with interruption of printing based on job information registered in one of the basic print queue and the backup print queue, registering backup job information in the print queues except the print queue corresponding to the printing apparatus which has interrupted printing.

Method and apparatus for executing load distributed printing

This invention provides a load distributed printing technique which efficiently uses a plurality of printing apparatuses by using small resources. To accomplish this, an information processing apparatus, which can transmit a print job to a plurality of printing apparatuses, is provided. The information processing apparatus comprises print queue setting means for setting one of a plurality of print queues corresponding to the plurality of printing apparatuses as a basic print queue and setting remaining print queues other than the basic print queue as backup print queues, print job registration means for registering print job information in the basic print queue, backup job registration means for generating backup job information corresponding to the print job information registered in the basic print queue and registering the backup job information in the backup print queue, and job control means for, when the print job information is registered in each of the basic print queue and the backup print queue, preferentially outputting a print job corresponding to the print job information to a corresponding printing apparatus, and when no print job information is registered, and a print job corresponding to the backup job information can be output, changing the backup job information to print job information and outputting the print job to a corresponding 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

There is disclosed a system which efficiently and effectively executes printing even when an error occurs in a printing apparatus. An apparatus according to the present invention is an information processing apparatus which includes a plurality of print queues corresponding to a plurality of printing apparatuses, comprising registration means for registering, in the plurality of print queues, job information including information which can link to print data, and means for excluding, from schedule-up targets, job information except job information scheduled up first in accordance with a vacant state of the print queues, and when interruption of printing has occurred in a printing apparatus which has output a print job based on the job information scheduled up, setting the job information excluded from the schedule-up targets as a schedule-up target.

A print processing result can be more certainly obtained while reducing a processing load of a printer. A print server forms a job tracing ID for a print job whose processing result is to be confirmed and transmits to a network printer. Thereafter, when the print job is formed in the network printer, the print server obtains information of the print job from the network printer. The job tracing ID has been allocated to the information of the print job. If it is decided based on the job tracing ID included in the information of the print job that the obtained information of the print job is not the information of the print job which is being traced, the print server determines that the print job which is being traced has been extinguished. The print server inquires the processing result of the extinguished print job from the network printer by using the job tracing ID.

Print managing apparatus, print managing method, and computer program

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

An object is to provide a scheme that holds back loads born by a print controlling apparatus capable of communication with an information processor, secure a constant level of usability related to printing by users and can establish a highly reliable printing system. With a scheme in an information processor including an issuing unit for issuing a request for process to a print controlling apparatus, a load is calculated for each of a number of requests that have been issued from the information processor but have received no response from the print controlling apparatus, and issuance of requests from the information processor is restrained based on the calculated loads.

Print controlling program, process method, recording medium, information processor and printing system

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 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.
