Patent ID: 8289555

Claim:
A print system comprising: a print server configured to receive print job data from a terminal device; and a first printer and a second printer configured to receive the print job data and to execute printing, each of the first printer and the second printer includes: a job-data communication unit configured to receive the print job data from the print server; a job-processing-result notification unit configured to provide the print server with a page-by-page of print completion information; and a transfer request unit configured to transmit a request to transfer print job data corresponding to the print job to the print server; a job data storage unit configured to store the print job data received from the print server and store the page-by-page print completion information; and the print server includes: a job-related-notification communication unit configured to receive the page-by-page print completion information from the job-processing-result notification unit; a job-data accumulation unit configured to accumulate the print job data received from the terminal device and to accumulate, in association with the print job data, the page-by-page print completion information; and a job-data transfer unit configured to transfer, in response to the transfer request from the transfer request unit, the print job data accumulated in the job-data accumulation unit to a printer that generated the transfer request, wherein if a failure occurs in the second printer, the job-processing-result notification unit of the second printer is configured to provide an occasion of the failure to the print server and the second printer is configured to interrupt the print job; the transfer request unit of the first printer is configured to transmit the transfer request of the print job data corresponding to the interrupted print job to the print server; and if the print job data is not transmitted from the print server in response to the transfer request, the transfer request unit of the first printer is configured to transmit the transfer request of the interrupted print job to the second printer interrupting the print job.
