1.OUTLINE

This LSI, through use of the Japan CBM Corp. gate array, serves to control CITIZEN line thermal printer, being featured by the following:

(1)High print quality due to a detector which detects temperature to adjust print density automatically.

(2)Both parallel and serial interfaces are available.

(3)Print density can be freely selected with the function selection terminal.

(4)Bar-code printing is available.

(5)Prints such as double width, double high and bit image printing are available by various commands.
