Abstract

A client terminal is provided with a print proxy which converts a request from a standard port monitor into a request to a print server and relays the request. This makes it possible to use an extension function between the client terminal and the print server in a system in which only the standard port monitor operates.

First claim

What is claimed is:

1 . An information processing apparatus which communicates with a print server which manages a printer, the apparatus comprising:
a receiver configured to receive, via a spooler, printing data generated by a printer driver corresponding to a printer object managed by information of a virtual printer corresponding to the print server, when performing printing by using the printer object; a specifying unit configured to specify job information including document information from the received printing data; and a controller configured to control transmission of the printing data and the specified job information with respect to the print server, wherein the controller performs at least one of compression transmission of the printing data, band limitation control of a network between the information processing apparatus and the print server, and retry processing for printing.

2 . The apparatus according to claim 1 , wherein a printing request issued from the printer driver via the spooler complies with IPP (Internet Printing Protocol).

3 . The apparatus according to claim 2 , further comprising an acquisition unit configured to acquire, when a virtual printer at a destination address is a storage-only virtual printer, printer information including a printer driver name associated with the storage-only virtual printer from the spooler,
wherein the controller controls transmission of the printing data and the printer driver name.

4 . The apparatus according to claim 2 , further comprising a message converter configured to convert a message between a message complying with a protocol with the print server and a message complying with IPP.

5 . The apparatus according to claim 1 , wherein the receiver receives the printing data further via a standard port monitor incorporated in an operating system which manages the information processing apparatus.

6 . The apparatus according to claim 1 , wherein the controller performs at least one of compression transmission of the printing data, band limitation control of a network between the information processing apparatus and the print server, and retry processing for printing based on preset transfer setting information.

7 . The apparatus according to claim 1 , wherein when a printer information acquisition request is received from the spooler, a request for corresponding virtual printer information from registered virtual printer information is issued with respect to the print server, and virtual printer information acquired in accordance with the request is transmitted to the spooler.

8 . A control method performed by an information processing apparatus which communicates with a print server which manages a printer, the method comprising:
receiving, via a spooler, printing data generated by a printer driver corresponding to a printer object managed by information of a virtual printer corresponding to the print server, when performing printing by using the printer object; specifying job information including document information from the received printing data; and controlling transmission of the printing data and the specified job information with respect to the print server, wherein in the controlling, at least one of compression transmission of the printing data, band limitation control of a network between the information processing apparatus and the print server, and retry processing for printing is performed.

9 . A non-transitory computer-readable storage medium recording a program which causes, when loaded into an information processing apparatus which communicates with a print server which manages a printer and executed, the information processing apparatus to execute a process, the process comprising:
receiving, via a spooler, printing data generated by a printer driver corresponding to a printer object managed by information of a virtual printer corresponding to the print server, when performing printing by using the printer object; specifying job information including document information from the received printing data; and controlling transmission of the printing data and the specified job information with respect to the print server, wherein in the controlling, at least one of compression transmission of the printing data, band limitation control of a network between the information processing apparatus and the print server, and retry processing for printing is performed.
