Printing apparatus and printing system, control method, storage medium and program

摘要

A printing apparatus which quickly cancels a print job without any influence on the subsequent other print jobs when a print cancel instruction is issued. During printing, if a print cancel instruction is inputted from a printer operation unit 107, a printer function manager 109 notifies a print command interpreter 108 of the cancellation. The print command interpreter 108 searches data processed at that time in a transmission/reception buffer for an end mark command indicating the end of the cancelled job. Then the print command interpreter 108 deletes the data before the end mark command.
