8 dot double density bit image

<ESC> “L” n1 n2 m1 m2...

(1B)H (4C)H n1 n2 m1 m2...

1 n1 + 256 × n2 400

Executes double density bit image printing (half-dot print- ing) determined by “ n1” and “ n2”. The total number of bit image data bytes in one line is equal to n1 + n2 × 256. Refer to <ESC> K as to the relation between the dot position and the bit number. The printer ignores any data bytes over the specified amount allowed in one line.

The printer does not print adjacent dots. When the bit image printing is finished, the printer automatically returns to the character mode.

For double density bit image printing, dots cannot be printed overlapping each other in the horizontal direction.

The following is an example of this.

When printing one graphic image of a minimum of two lines with <ESC> K or <ESC>L, feed the paper a minimum of one line before printing so that the line spacing becomes identical between the lines.
