Printer with command system selection

摘要

A printer has a collective mode for searching a print control program adapted to the processing of print data from a number of print control programs stored in a printer and a combination mode for searching an adapted print control program from combinations of predetermined print control programs. The modes are selected by a key of a switch panel. From the print data, the control code for determining the print control command system is analyzed, and a print control program adapted to the analyzed control code is searched from the print control programs of each mode. This system enables the accurate determination of a print control program adapted to a print data processing a number of print control programs having different command systems for print control.
