Disclosed are a print control method and a print control apparatus capable of recognizing status information pertaining to a printer, and selecting a time interval at which the transmission of updated status information is to be requested of the printer from among a plurality of preset time intervals, in accordance with the current status information of the printer. This reduces the time lag between a change of status of the printer and the status information of the printer displayed by the print control apparatus, and avoids deterioration of the performance of the print control apparatus and the printer.
