Abstract

PURPOSE:To process the other drive system during the processing of the cut- form data for one drive system by a method wherein before the printing of a drive system to be driven this time is completed, an instruction of indicating a drive system to be driven next time is received, and the cut-form is set to a printing position by driving one of the drive systems. CONSTITUTION:At the reception of data, whether present device control data 22a instructs a first drive system or a second drive system is judged. When the presence of next cut-form data is judged by next device control data 23a, the cut-form data is printed by the first drive system, and whether next printing is made by the first drive system or the second drive system is judged. When the next printing is made by the second drive system, the cut-form of the second drive system is set to a first character printing position. As a result, the cut- form is completely set to the first line printing position in the second drive system during the printing of the first drive system. After the last line of the cut-form of the first drive system is completed, the printing of the data is immediately started because the cut-form of the second drive system has already set to the first line printing position.
