Abstract

A client terminal in a network printing system including the client terminal, a control server which controls processing for an online document on a network, and an image forming apparatus, comprises a print instruction unit configured to send a print instruction for the online document to the control server by executing processing defined in a script language for the online document accessed via a Web browser of the client terminal, wherein the processing defined in the script language is registered as a bookmarklet in the Web browser, and when printing the accessed online document, processing of the print instruction unit is executed in response to selecting the bookmarklet by a user.

Claims

1. A network printing system comprising a client terminal, a control server which controls processing for an online document on a network, and an image forming apparatus,

said client terminal comprises a print instruction unit configured to send a print instruction for the online document to said control server by executing processing defined in a script language for the online document accessed via a Web browser of said client terminal, and

said control server comprises:

a format determination unit configured to receive the print instruction sent from said client terminal, and to determine whether the online document designated by the print instruction has a document format printable by the image forming apparatus;

a conversion determination unit configured, when said format determination unit determines that the online document is unprintable, to determine whether a document format of the online document designated by the print instruction can be converted;

a conversion unit configured, when said conversion determination unit determines that the document format can be converted, to convert the document format of the online document into a printable document format; and

an input unit configured to input actual data of the online document of the printable document format as a printing target in the image forming apparatus.

2. The system according to claim 1, wherein in said client terminal, the processing defined in the script language is registered as a bookmarklet in the Web browser, and when printing the accessed online document, processing of said print instruction unit is executed in response to selecting the bookmarklet by a user.

3. The system according to claim 1, wherein in the processing defined in the script language in said client terminal, the online document is specified from a URL of the online document accessed by a user.

4. The system according to claim 1, wherein said control server further comprises

a storage unit configured to store the online document when the online document designated by the received print instruction is unprintable, and

a notification unit configured, when a print instruction is issued for an online document identical to the online document stored in said storage unit, to notify a user that the online document is unprintable, without acquiring actual data of the online document.

5. The system according to claim 1, wherein

when executing the processing defined in the script language for the online document accessed via the Web browser of said client terminal, said print instruction unit of said client terminal determines whether the online document has been encrypted, and when the online document has been encrypted, further sends information about encryption of the online document to said control server, and

said control server further comprises

a storage unit configured to store the online document when said control server receives the print instruction sent from said client terminal and determines, based on the information about encryption, the online document designated by the print data to be unprintable owing to encryption, and

a notification unit configured, when a print instruction is issued for an online document identical to the online document stored in said storage unit, to notify a user that the online document is unprintable, without acquiring actual data of the online document.

6. The system according to claim 1, wherein said control server further comprises

an acquisition unit configured to acquire information about a page count of the online document, and

a sending unit configured to send, to said client terminal, a setting screen which displays only a print setting selectable for the page count acquired by said acquisition unit.

7. The system according to claim 1, wherein information about an online document stored in a storage unit of said control server includes at least a URL of the online document, a document format, document format conversion possible/impossible information, and print setting information.

8. A client terminal in a network printing system including the client terminal, a control server which controls processing for an online document on a network, and an image forming apparatus, comprising a print instruction unit configured to send a print instruction for the online document to the control server by executing processing defined in a script language for the online document accessed via a Web browser of the client terminal,

wherein the processing defined in the script language is registered as a bookmarklet in the Web browser, and when printing the accessed online document, processing of said print instruction unit is executed in response to selecting the bookmarklet by a user.

9. A printing method in a network printing system including a client terminal, a control server which controls processing for an online document on a network, and an image forming apparatus, comprising:

in the client terminal,

a print instruction step of sending a print instruction for the online document to the control server by executing processing defined in a script language for the online document accessed via a Web browser of the client terminal;

in the control server,

a format determination step of receiving the print instruction sent from the client terminal, and determining whether the online document designated by the print instruction has a document format printable by the image forming apparatus;

a conversion determination step of, when the online document is determined in the format determination step to be unprintable, determining whether a document format of the online document designated by the print instruction can be converted;

a conversion step of, when the document format is determined in the conversion determination step to be able to be converted, converting the document format of the online document into a printable document format; and

an input step of inputting actual data of the online document of the printable format as a printing target in the image forming apparatus.
