Abstract

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.

Claims15

Dependent claims

An information processing apparatus which can communicate with a plurality of printing apparatuses, comprising:

a detection unit that detects in one printing apparatus an occurrence of an event in which printing is disabled;
a first identification unit that identifies, in response to detection performed by the detection unit, print jobs which are issued by the information processing apparatus among a plurality of print jobs managed by a print queue of the printing apparatus;
an obtaining unit that obtains information indicating a status of each of the print jobs in the printing apparatus;
a second identification unit that identifies, in response to detection performed by the detection unit, a first print job which is to be processed first and print jobs other than the first print job from among the plurality of print jobs managed by the print queue of the printing apparatus, based on the information indicating a status of each of the print jobs in the printing apparatus;
a transfer unit that transfers, in response to detection performed by the detection unit, the print jobs other than the first print job and identified by the first identification unit from among the plurality of print jobs to another printing apparatus without transferring the first print job and the print job not being identified by the first identification unit to the another printing apparatus;
a deletion unit that deletes, in response to detection performed by the detection unit, the print jobs other than the first print job and identified by the first identification unit from among the plurality of print jobs from the printing apparatus while leaving the first print job in the printing apparatus;
and
a selection unit that selects via a setting screen, a first substitution mode in which all print jobs which are identified by the first identification unit are printed by another printing apparatus in place of the printing apparatus or a second substitution mode in which print jobs, other than the first print job, which are identified by the first identification unit are printed by another printing apparatus in place of the printing apparatus, wherein the second identification unit functions when the second substitution mode is selected.

5 more elements

An information processing system which can communicate with a plurality of printing apparatuses, the system comprising:

detection means for detecting in one printing apparatus the occurrence of an event in which printing is disabled;
first identification means for identifying, in response to detection performed by the detection means, print jobs which are issued by the information processing apparatus among a plurality of print jobs managed by a print queue of the printing apparatus;
second identification means for identifying, in response to detection performed by the detection means, a first print job which is to be processed first and print jobs other than the first print job from among the plurality of print jobs managed by the print queue of the printing apparatus;
transfer means for transferring, in response to detection performed by the detection means, the print jobs other than the first print job and identified by the first identification means from among the plurality of print jobs to another printing apparatus without transferring the first print job and the print job not identified by the first identification unit to the other printing apparatus;
deletion means for deleting, in response to detection performed by the detection means, the print jobs other than the first print job and identified by the first identification means from among the plurality of print jobs from the printing apparatus while leaving the first print job in the printing apparatus;
and
selection means for selecting, via a setting screen, a first substitution mode in which all print jobs which are identified by the first identification means are printed by another printing apparatus in place of the printing apparatus or a second substitution mode in which print jobs, other than the first print job, which are identified by the first identification means which are printed by another printing apparatus in place of the printing apparatus, wherein the second identification means functions when the second substitution mode is selected.

4 more elements

A method for managing print jobs in a plurality of printing apparatuses, the method comprising:

a detection step of detecting in one printing apparatus the occurrence of an event in which printing is disabled;
a first identification step of identifying, in response to detection performed by the detection means, print jobs which are issued by the information processing apparatus among a plurality of print jobs managed by a print queue of the printing apparatus;
a second identification step of identifying, in response to detection performed in the detection step, a first print job which is to be processed first and print jobs other than the first print job from among the plurality of print jobs managed by the print queue of the printing apparatus;
a transfer step of transferring, in response to detection performed in the detection step, the print jobs other than the first print job and identified by the first identification step from among the plurality of print jobs to another printing apparatus without transferring the first print job and the print job not identified by the first identification unit to the another printing apparatus;
a deletion step of deleting, in response to detection performed in the detection step, the print jobs other than the first print job and identified by the first identification step from among the plurality of print jobs from the printing apparatus while leaving the first print job in the printing apparatus;
and
a selection step for selecting, via a setting screen, a first substitution mode in which all print jobs which are identified by the first identification step are printed by another printing apparatus in place of the printing apparatus or a second substitution mode in which print jobs, other than the first print job, which are identified by the first identification step which are printed by another printing apparatus in place of the printing apparatus, wherein the second identification step functions when the second substitution mode is selected.
