ESC * m nL nH [d]k

[Function] Selects Bit Image Mode

[Code] ASCII ESC * m nL nH [d] k

Hexadecimal 1B 2A m nL nH [d] k

Decimal 27 42 m nL nH [d] k

[Range] m = 0, 1

0  nL  255

0  nH  3

0  d  255

k = nL  nH × 256

[Outline] • This command speciﬁes the bit image of the m-mode as to the number of dots speciﬁed with

nL and nH.

• nL and nH denote the number of horizontal dots of the bit image to be printed, resulting in [nL

+ nH × 256] dots.

• If the bit image data is input beyond the dot position printable in one line, the surplus data will

be discarded.

• d denotes the bit image data. Set "1" in the corresponding bit when printing, and "0" when

not printing.

• The following table lists the bit image mode selected with m.

[Caution] • If a value of m or nH goes beyond the range, this command will be ignored, processing the

subsequent data as normal one.

• Normal data processing is restored after printing the bit image.

• The following page shows the relations between the bit image data and the dots printed.

• The double density bit image is invalidated in the page mode.

*1: The total number of horizontal dots in the page mode differs depending on the printing area

secured with ESC W and printing direction speciﬁed with ESC T.
