PRINTING SYSTEM, PRINTING CONTROL METHOD IN CLUSTER ENVIRONMENT, AND PRINTING CONTROL PROGRAM

摘要

A print job is submitted from a client terminal 100 to two print servers 200−1, 200−2, a print server taking main charge 200−1 instructs a printer 300 to print one page at a time in sequence, and status information indicating the printing state is shared by the two print servers 200−1, 200−2. If a failure occurs in the print server taking main charge 200−1, then, on the basis of the status information shared by the two print servers 200−1, 200−2, a print server taking sub charge 200−2 instructs the printer 300 to print in accordance with the submitted print job from the unprinted page. This makes it possible to immediately continue the print from the page indicated to be completely printed when the failure occurred.

主权项

1. A printing system in a cluster environment having a plurality of print servers, the printing system comprising:
a print job submitting unit for submitting a print job generated in a client terminal into at least two of the print servers; a print executing control unit for sequentially giving a printer instructions for executing print for respective pages in accordance with respective commands based on the print job and receiving print completion notices for respective pages from the printer in a print server into which the print job is submitted by the print job submitting unit; a status information share managing unit for generating status information indicating which pages have been completely printed based on the print completion notice received from the printer by the print executing control unit and storing the status information in storing units of the at least two print servers, respectively; and a server failure occurrence detecting unit for detecting occurrence of a failure in the print server, wherein the print executing control unit sequentially gives the printer instructions for executing print from a first page in one of the at least two print servers into which the print job is submitted by the print job submitting unit, and when the occurrence of the failure in the one print server is detected by the server failure occurrence detecting unit, the print executing control unit sequentially gives the printer instructions for executing print from a next unprinted page to a page indicated to be completely printed through the status information stored in the storing unit based on the print job which has been submitted by the print job submitting unit in another print server from the print server having the failure occurrence in the at least two print servers.
