A printing apparatus for performing printing by scanning a carriage capable of mounting an inkjet printhead discharging ink where correction of printing timing is performed for adjusting printing positions in the printing, and information on the correction, which can be obtained when the correction is executed, is stored in non-volatile memory means.

Printing apparatus, printing system and control method for printing apparatus

An inkjet printing apparatus, having a carriage incorporating an inkjet printhead where nozzles for discharging ink are arranged in a predetermined direction, performs printing by scanning the carriage with respect to a printing medium in a direction orthogonal to the nozzle arrangement direction. The apparatus includes first and second conveyance sections, which are arranged at the front and rear of the area scanned by the printhead, for holding and conveying the printing medium. When the printing medium is held only by one of the conveyance sections, nozzles to be used for printing are selected from the nozzles satisfying the condition that the distance between a discharge surface of the nozzle and a printing surface of the printing medium falls within a predetermined range, in accordance with a position of the printing medium with respect to the printing-medium conveyance direction.

Inkjet printing apparatus and control method for the same

A printing apparatus can quickly cancel a print job without any influence on the other subsequent print jobs when a print cancel instruction is issued. During printing, if a print cancel instruction is inputted from a printer operation unit, a printer function manager notifies a print command interpreter of the cancellation. The print command interpreter 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 deletes the data before the end mark command.
