[Description]

Stores the bit image data in the print buffer using the mode specified by bit image mode m as follows:
m
Bit image Mode
Number of bits for vertical data
Dot density in horizontal

8-dot single-density

8-dot double-density

  • nL, nH specifies a bit image in the horizontal direction as (nL + nH × 256) dots.
  • d specifies the bit image data (column format).
  • k indicates the amount of bit image data. k is an explanation parameter; therefore it does not need to be transmitted.

[Notes]

  • Data (d) specifies a bit printed to 1 and not printed to 0.
  • If the bit image data exceeds the number of dots to be printed on a line, the excess data is ignored.
  • The bit-image is not affected by print mode (emphasized, double-strike, underline, character size, white/black reverse printing, or 90° clockwise-rotated), except for upside-down print mode.
  • After printing a bit image, the printer processes normal data.
  • When printing multiple line bit images, selecting unidirectional print mode with ESC U enables printing patterns in which the top and bottom parts are aligned vertically.
  • This command is used to print a picture or logo.
  • The relationship between the bit image data and the print result is as follows.
    • 8 dot mode (m = 0, 1)
    • Graphic
    • 24 dot mode (m = 32, 33)
    • Graphic
