Printing system in which programs required for printer operation are downloaded from computer

Abstract

A printing system that comprises a host computerand a printerin combination. As the printeris used one that can process a first class print request including a control program and print data and a second class print request including only print data, and, when an ID output request is received, sends a control program ID as identification information of a control program stored inside the printerat that point of time. Printer control softwareis installed on the host computerto put the computerin a state that, when a print request is to be outputted to the printerthe computerverifies whether a required control program is stored within the printerand the computersends a second class print request to the printerwhen storing of the control program is verified, and sends a first class print request to the printerwhen storing of the control program is not verified. Thus, it is possible to realize a printing system including a such type of printer that can process print data of various language and downloads a control program, having a shorter average time required for printing.
