Abstract

In print systems based on data reception from a server, it takes much time to receive data of a large size. Therefore systems have been developed in which data is divided before being received. However, if divided data items are received by a print device while temperature adjustment or calibration is performed for an engine of the device, the divided data items are not immediately printed, resulting in a long print time. A print device sequentially receives divided data items if the print device is in a printable status. Otherwise, the print device simultaneously receives the divided data items in a plurality of sessions.

Claims

1. A network print system including a print device and a server system,

the server system comprising:

a dividing unit, configured to divide an uploaded original document file into a plurality of document files if the original document file has a data size exceeding a threshold;

a generating unit, configured to generate a job ticket for printing the plurality of divided document files;

a saving unit, configured to save the plurality of divided document files and the job ticket as a print job; and

a transmitting unit, configured to transmit the saved job ticket in response to a request from the print device, and

the print device comprising;

a request unit, configured to transmit, upon input of a print instruction to print the original document file, the request to the server system; and

a receiving unit, configured to, when the print device is in a printable status, receive from the server system the plurality of divided document files in an order described in the job ticket received from the server system in response to the request,

wherein the receiving unit, when the print device is in an unprintable status, receives from the server system the plurality of divided document files in parallel regardless of the order described in the job ticket.

2. The network print system according to claim 1, wherein a structure of the document file is described at the end of the document file.

3. A method for downloading document data in a network print system including a print device and a server system, the method comprising:

the server system dividing an uploaded original document file into a plurality of document files if the original document file has a data size exceeding a threshold;

the server system generating a job ticket for printing the plurality of divided document files;

the server system saving the plurality of divided document files and the job ticket as a print job;

upon input of a print instruction to print the original document files, the print device transmitting the request to the server system;

the server system transmitting the saved job ticket in response to the request from the print device;

when the print device is in a printable status, the print device receiving from the server system the plurality of divided document files in an order described in the job ticket received from the server system in response to the request,

wherein, when the print device is in an unprintable status, the print device receives from the server system the plurality of divided document files in parallel regardless of the order described in the job ticket.

4. A server system connected with a print device and including a storage unit for saving externally an uploaded document file described in PDF (Portable Document Format), the server system comprising:

a dividing unit, configured to divide the uploaded document file into a plurality of document files,

a generating unit, configured to generate a job ticket for printing the plurality of divided document files;

a saving unit, configured to save the plurality of divided document files and the job ticket in the storage unit; and

a transmitting unit, configured to transmit the plurality of divided document files and the job ticket saved in the storage unit in response to a request for printing from the print device,

wherein the transmitting unit transmits the plurality of divided document files in an order described in the generated job ticket when the print device is in a printable status, and

the transmitting unit transmits the plurality of divided document files in parallel when the print device is in an unprintable status.

5. The server system according to claim 4, wherein said transmitting unit further transmits the undivided original document file saved in the storage unit if the request from the print device specifies that the document file is to be saved after being printed.

6. The server system according to claim 4, wherein the document file includes setting information in which specification of two-sided printing or one-sided printing and a page layout are set, and

said dividing unit refers to the setting information to divide the document file on the basis of separation between sheets of a printed sheet medium.

7. A non-transitory storage medium having recorded therein a program for causing a computer to function as each unit included in the server system according to claim 4.

8. A method in a server system connected with a print device and including a storage unit for saving externally an uploaded document file described in PDF (Portable Document Format), the method comprising:

dividing the uploaded document file into a plurality of document files;

generating a job ticket for printing the plurality of divided document files;

saving the plurality of divided document files and the job ticket in the storage unit; and

transmitting the plurality of divided document files and the job ticket saved in the storage unit in response to a request for printing from the print device,

wherein the plurality of divided document files are transmitted in an order described in the generated job ticket when the print device is in a printable status, and

the plurality of divided document files are transmitted in parallel when the print device is in an unprintable status.

9. A print device connected with a server system, the print device comprising:

a request unit, configured to transmit, upon input of a print instruction to print a document file saved in the server system, a request for receiving a job ticket of the document file from the server system;

a receiving unit, configured to, when the print device is in a printable status, receive from the server system a plurality of divided document files in an order described in the job ticket received from the server system in response to the request; and

a printing unit, configured to perform printing by using the plurality of divided document files received by said receiving unit,

wherein the receiving unit, when the print device is in an unprintable status, receives from the server system the plurality of divided document files in parallel regardless of the order described in the job ticket.

10. The print device according to claim 9, wherein said receiving unit receives the document file with a limited reception band if the print device is executing another print job.

11. The print device according to claim 9, wherein a structure of the document file is described at the end of the document file.

12. The print device according to claim 9, further comprising

a saving unit, configured to save the undivided original document file received from the server system in the storage unit if it is specified that the document file instructed to be printed is to be saved in the storage unit.

13. A method in a print device connected with a server system, the method comprising:

upon input of a print instruction to print document files saved in the server system, transmitting a request for receiving a job ticket of the document file from the server system;

when the print device is in a printable status, receiving from the server system a plurality of divided document files in an order described in the job ticket received from the server system in response to the request;

when the print device is in an unprintable status, receiving from the server system the plurality of divided document files in parallel regardless of the order described in the job ticket; and

performing printing by using the plurality of divided document files received.

14. The method according to claim 13, further comprising:

saving the undivided original document file received from the server system in the storage unit if it is specified that the document file instructed to be printed is to be saved in the storage unit.
