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.

2. The print system according to claim 1 , wherein

the job data communication unit of the second printer is configured to transmit the job data stored in the job data storage unit of the second printer to the first printer, in response to the transfer request of the interrupted print job from the first printer.

3. The print system according to claim 2 , wherein

the job-data communication unit of the first printer receives the print job data transmitted from the second printer in response to the transfer request.

4. The print system according to claim 1 , wherein

the transfer request unit transmits the identification code of the print job data to the print server upon the transfer request; and

the job-data transfer unit compares the identification code transmitted from the transfer request unit against the identification code of the print job data accumulated in the job-data accumulation unit, and only if the two identification codes match, the job-data transfer unit transfers the print job data.

5. A non-transitory computer-readable recording medium that stores printing program codes that are executed by a first printer computer, a second printer computer, and a print server computer, the printing program codes comprising:

a first program code for causing the print server computer to receive print job data from a terminal device and to accumulate the print job data;

a second program code for causing the first and second printer computers to receive the print job data from a print server;

a third program code for causing the first and second printer computers to print the print job data;

a fourth program code for causing the first and second printer computers to provide the print server with page-by-page print completion information;

a fifth program code for causing the print server computer to receive the page-by-page print completion information from a first printer;

a fifth program code for causing the print server computer to accumulate the page-by-page print completion information in association with the print job data;

a sixth program code for causing the first and second printer computers to transmit a request to transfer print job data corresponding to interrupted print job to the print server;

a seventh program code for causing the print server computer to transfer, in response to the transfer request from the first printer, the accumulated print job data to a printer that generated the transfer request; and

an eighth program code for causing the first and second printer computers to store the print job data received from the print server and store the page-by-page of print completion information, wherein

if a failure occurs in a second printer, the third program code causes the second printer computer to provide an occasion of the failure to the print server and interrupt the print job;

the sixth program code causes the first printer computer to transmit the transfer request of the print job data corresponding 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 sixth program code causes the first printer computer to transmit the transfer request of the interrupted print job to the second printer interrupting the print job.

6. The non-transitory computer-readable recording medium according to claim 5 , the printing program codes further comprising

a ninth program code for causing the second printer computer to transmit the job data stored in the second printer to the first printer, in response to the transfer request of the interrupted print job from the first printer.

7. The non-transitory computer-readable recording medium according to claim 6 , wherein

the second program code causes the first printer computer to receive the print job data transmitted from the second printer in response to the transfer request.

8. The non-transitory computer-readable recording medium according to claim 5 , wherein

the sixth program code causes the first and second printer computers to transmit the identification code of the print job data to the print server upon the transfer request; and

the seventh program code cases the print server computer to compare the identification code transmitted from the transfer request unit against the identification code of the print job data accumulated in the job-data accumulation unit, and only if the two identification codes match, the seventh program code cases the print server computer to transfer the print job data.

9. A method of printing by a first printer, a second printer, and a print server comprising the steps of:

causing a-first and second printer computers to receive a print job data from the print server;

causing the first and second printer computers to print the print job data;

causing the first and second printer computers to provide the print server with page-by-page print completion information;

causing the print server computer to receive the page-by-page print completion information from the first printer;

causing the print server computer to accumulate the page-by-page print completion information in association with the print job data;

causing the first and second printer computers to transmit a request to transfer print job data corresponding to an interrupted print job to the print server;

causing the print server computer to transfer, in response to the transfer request from the first printer, the accumulated print job data to a printer that generated the transfer request; and

causing the first and second printer computers to store the print job data received from the print server and store the page-by-page of print completion information, wherein

if a failure occurs in the second printer, the second printer provides an occasion of the failure to the print server and interrupts the print job;

the first printer transmits 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 first printer transmits the transfer request of the interrupted print job to the second printer interrupting the print job.

10. The method according to claim 9 wherein

the second printer transmits the job data stored in the job data storage unit of the second printer to the first printer, in response to the transfer request of the interrupted print job from the first printer.

11. The method according to claim 10 , wherein

the first printer receives the print job data transmitted from the second printer in response to the transfer request.

12. The method according to claim 9 , wherein

the first and second printer transmit the identification code of the print job data to the print server upon the transfer request; and

the print server compares the identification code transmitted from the transfer request unit against the identification code of the print job data accumulated in the job-data accumulation unit, and only if the two identification codes match, the print server transfers the print job data.
