Abstract

A processing device has a requesting section that issues a request to transmit processing data to a server; a receiving section that receives the processing data transmitted from the server in response to the request; a processing section that sequentially makes the received processing data a processing object, and conducts processing based on the processing data that is made a processing object; and a measuring section that measures a data amount of the processing data that has been made a processing object among the received processing data. In a case where a session between the server is disconnected before all the processing data is made a processing object and thereafter the session is reconnected, the processing section conducts processing with respect to a portion that is not yet made a processing object based on the data amount have measured when the server is disconnected.

Claims

1. A processing device comprising:

a requesting section that issues a request to transmit processing data to a server;

a receiving section that receives the processing data transmitted from the server in response to the request to transmit;

a processing section that sequentially makes the processing data received by the receiving section a processing object, and conducts processing based on the processing data that is made a processing object; and

a measuring section that measures a data amount of the processing data that has been made a processing object by the processing section among the received processing data, wherein

in a case where a session between the server is disconnected before all the processing data is made a processing object and thereafter the session is reconnected, after the session is reconnected, the processing section conducts processing with respect to a first portion that is not yet made a processing object among the processing data based on the data amount have measured by the measuring section when the server is disconnected and does not conduct processing with respect to a second portion that is already made a processing object among the processing data.

2. The processing device according to claim 1, wherein in a case where a session between the server is disconnected before all the processing data is made a processing object and thereafter the session is reconnected, the requesting section issues a request to transmit the first portion that does not include the second portion based on the data amount measured by the measuring section after the session is reconnected.

3. The processing device according to claim 2, wherein in a case where the processing data received after the session is reconnected is the first portion only, the processing section makes the portion of the processing data a processing object, and in a case where the processing data received after the session is reconnected includes the first portion and the second portion, the processing section extracts the first portion from the received processing data based on the data amount measured by the measuring section and makes the first portion a processing object.

4. The processing device according to claim 1, wherein in a case where a session between the server is disconnected before all the processing data is made a processing object and thereafter the session is reconnected, the processing section extracts the first portion based on the data amount measured by the measuring section from the processing data received by the receiving section in response to the request to transmit the processing data issued again by the requesting section, and makes the first portion a processing object.

5. The processing device according to claim 1, wherein in a case where the processing section ceases to acquire the processing data before the acquisition of the processing data is completed and thereafter the processing data is acquired again, the processing section conducts processing to the first portion when the reason why the acquisition of the processing data is ceased is classified into a first group, and the processing section conducts processing to the first portion and the second portion when the reason why the acquisition of the processing data is ceased is classified into a second group.

6. The processing device according to claim 1, wherein the receiving section causes a first storing section to store the received processing data, the processing section conducts processing before processing to the processing data stored in a second storing section as the processing object and conducts processing based on the data after processing before processing, and the measuring section measures the data amount of the processing data forwarded from the first storing section to the second storing section.

7. The processing device according to claim 1, wherein the requesting section issues a request to transmit a portion of the processing data that is not yet made a processing object through range specification by using a range header of HTTP.

8. The processing device according to claim 1, wherein the processing data is print data, and the processing section is a processing section that conducts printing based on the acquired print data.

9. The processing device according to claim 5, wherein the processing data is print data, the processing section is a processing section that conducts printing based on the acquired print data, the reason classified into the first group is the occurrence of at least any one of errors including no printing medium, no color material, a type mismatch of a printing medium and open device cover, and the reason classified into the second group is the occurrence of at least any one of errors including a printing medium jam, mechanical abnormality of the processing section and a power outage.

10. A processing method comprising:

issuing a request to transmit processing data to a server;

receiving the processing data transmitted from the server in response to the request to transmit;

sequentially making the processing data received by the receiving section a processing object, and conducts processing based on the processing data that is made a processing object; and

measuring a data amount of the processing data that has been made a processing object by the processing section among the received processing data, wherein

in a case where a session between the server is disconnected before all the processing data is made a processing object and thereafter the session is reconnected, in the processing step, after the session is reconnected, processing is conducted with respect to a first portion that is not yet made a processing object among the processing data based on the data amount have measured in the measuring when the server is disconnected, and processing is not conducted with respect to a second portion that is already made a processing object among the processing data.

11. A server comprising:

a storing section that stores processing data to be processed by a data processing device; and

a transmitting section that transmits the processing data to the data processing device, wherein

in a case where the transmitting section ceases to transmit the processing data before completing transmission of the entire processing data and thereafter the transmitting section transmits the processing data again, the transmitting section transmits a portion of the processing data including a portion of the entire processing data that is not yet transmitted when the reason why the transmission of the processing data is ceased is classified into a first group, and transmits the entire processing data when the reason why the transmission of the processing data is ceased is classified into a second group.
