PURPOSE: To permit setting of 'printing mode' which is frequently used, and also changing of the printing mode by providing an initialization means to set the initial state of panel switch when a power supply is turned ON to a desired printing mode. CONSTITUTION: In a mechanism to set 'printing mode', the printing mode which is set by means each switch (Nos, 1 to 8) of a DIP switch 47 and each switch of a switch panel 3 can be changed within the limits of line pitches and printing pitches stored in ROM 77 in advance. That is, the line pitch can be set selectively by means of DIP switches Nos.1 and 2. At the same time, the printing pitch can be set to each mode such as 1/10, 1/12 and 1/15 inches by the switches Nos.3 and 4. If a power supply is turned ON, CPU 55 reads (S1) a setting state of the DIP switch 47 and sets a printing operation to the printing mode stored in ROM 77 based on the mentioned setting state. Next a printing pitch indicator lamp 27 and a line pitch indicator lamp 29 are turned ON in accordance with the printing mode. Each motor in controlled by means of the printing mode set in this manner, performing printing. COPYRIGHT: (C)1988,JPO&Japio
