Patent ID: 8767226

Claim:
A printing system in which a print server, a client apparatus, and an image output apparatus are connected via a network, wherein the image output apparatus includes: a first connection port for local connection and a second connection port for receiving a print job via the print server; a reply unit configured to send back an address of the second connection port upon receiving an address acquisition request; and a printing unit configured to print a print job received via the first connection port or the second connection port, wherein the print server includes: an image output apparatus registration unit configured to register an image output apparatus serving as a transmission destination of a print job; and a transmission unit configured to transmit a print job via a designated connection port to the image output apparatus which is set or designated by the print job and registered by the image output apparatus registration unit, wherein the client apparatus includes a first installer for installing a driver corresponding to the image output apparatus, the first installer being executed to install, in the client apparatus, a first driver and a second installer for installing a second driver, wherein, in installation by the first installer, the second driver is not installed and a print queue corresponding to the second driver is not displayed in a print queue list, wherein the installed first driver includes: a generation unit configured to generate a first print queue to connect to the first connection port of the image output apparatus; an address acquisition unit configured to transmit the address acquisition request and acquire the address of the second connection port of the image output apparatus; and an execution unit configured to, upon accepting an instruction to generate a second print queue using the print server as a connection destination, launch the second installer installed with the first driver when installed by the first installer to install the second driver, and generate the second print queue, wherein the second driver is displayed in the print queue list upon the generation of the second driver, and wherein the launched second installer generates the second print queue using the address of the second connection port that is acquired by the address acquisition unit.
