A model-specific database 27 provided on a print control member 11 of a printer stores setting commands for a plurality of print stations, and menu information to be displayed on an operation panel. A maintenance processing member 25 obtains from the model-specific database 27, a menu corresponding to the model ID 251 of the print station, and displays the menu on the operation panel exposed at the printer housing. A maintenance operator carries out adjustment of the print station by operating the operation panel. Since processes and the like depending on the model of the print station are concentrated in the maintenance processing member 25 and the model-specific database 27, other structures of the print control member 11 can be configured so as not to depend on the model of the print station.
