Abstract:

Code compression for a dot printer 1 having a printhead 3 with a vertical line of print elements 5. The coding reduces requirements for space in font memory 13 and is readily translated and acted upon. In each eight-bit byte, microprocessor 11 interprets three bits as coding mode commands and the other five bits as content information, primarily as numbers. Printer control code modes are: black in sequence, black in sequence, complete white, white in sequence, repeat column, map bytes (bit-for-bit), and offset. The content information number is stored in register 21 (19 for offset) and printing in the form defined by the code mode is executed the number of times as stored in the register 21 (19 for offset).
