PROBLEM TO BE SOLVED: To ensure version compatibility between a printer driver and a printer firmware by a low-cost method without automatically checking an external information site. SOLUTION: This version management and print processing system has: a means displaying printer information to the printer driver; a means receiving the version of the firmware from a printer; a means wherein the printer driver operates in a different firmware version; and a means reading a printer firmware version information DB (for managing a function, a printer command or the like added in each the firmware version) into the printer driver. The version of the firmware is acquired in a printer information screen, and the printer driver operates by use of a function of the old version from the printer firmware version information DB when the version is older than the firmware presently assumed by the driver.
