PURPOSE:To simplify the control for the style of type, by providing a type style setting terminal at an input port and carrying out the printing with the style of type which is designated by the state of the setting terminal. CONSTITUTION:The states of terminals S1-S3 are read when the corresponding address decode signal is turned on, and this state signal is transmitted onto a data bus via the output terminal of an input port and a gate 12. The switch state of a setting terminal 11 is read by an initial type style deciding routine. This routine is executed when the power supply is applied and at the starting moment of the printing of a line. Whether or not the terminal S1 is at logic ''0'' is first checked, and the pitch and the size are decided in the case of logic ''0''. |
