To allow a utility integrated into a host computer to inquire for an available printer connected with a network by broadcast, to down-load the printer driver of the responding printer, and to automatically install the available printer driver.

Relating to a host device 112, an application 116 transmits intermediate print data specific to an OS prepared through an OS 117 to a print driver 118 at the time of printing data. The driver 118 converts the received intermediate print data into a printer control command(final print data) peculiar to a printer 115, and transmits the data to a print manager 119. The manager 119 temporarily spools the print data for quickening printing processing of the application 116. An install utility 120 obtains information from the printer 115, and installs the printer driver.
