Abstract

PURPOSE: To realize a bold printing easily by adding a simple circuit without providing a special circuit or mechanism, by making a part of bit forming a character have the mechanism detecting whether the bold printing exists or not.
CONSTITUTION: When a printing data PRTDET is transferred from CPU, etc., it is stored in the buffer memory, etc. once, it is output in order through the data buses 10W12, and an alphanumeric code is input to the character discriminating circuit 1. This code is decoded by this circuit 1, and logic 1 is output to the A/N character line, the space line and the line corresponding to other character. And in case of bold printing, the sequential circuit of the 1 character printing control circuit 3 is operated by a data of the bolt bit line 12, and a strobe signal is output. In this way, the AND gate 7 is closed, the AND gate 6 is opened, the code such as an A/N character or a symbol, etc. through the data bus 10 from the buffer memory, etc. is made a data, and it is input to the printer interface circuit 4.
