8.10.10 BIT IMAGE MODE SELECT COMMAND
Function Selects bit image mode (or prints image data).
Format [ESC] *mnLnH (d1d2...d
Term ASCII: ESC *
Hex: 1Bh 2Ah
[Parameter]
m:
nL: No. of bytes in the horizontal direction (low order) 0 ≤ nL ≤ 255 (00h ≤ nL ≤ FFh)
nH: No. of bytes in the horizontal direction (high order) 0 ≤ nH ≤ 3 (00h ≤ nH ≤ 03h)
d:
k:
Explanation (1) Image data m is specified by the number of dots defined by nL, nH and k.
(2) The number of dots in the horizontal direction is determined by nL + 256 × nH.
(3) If the number of dots in the horizontal direction (nL + 256 × nH) exceeds the value
listed in the table below, printing will be performed while wrapping around, and
consequently corrupted.
(4) d refers to image data. A bit to be printed is set to 1, and the one not to be printed is set
to 0.
(5) The table below shows mode selected by m.
(6) Underlining, bold printing, reverse printing (white on black background), or inverted
printing (upside-down) is not applicable to this image data.
(7) A bit image in page mode is valid only when 0 (0-degree rotation) is specified by the
Page Mode Print Direction Set Command ([ESC] T). If anything other than 0
degree is selected, the bit image will not be rotated.
(8) At a moment when an error occurs with parameter m, nL, or nH due to a factor such
as an unmatched condition, command processing will be aborted, and the
subsequent data subsequent to x will be processed as normal data.
(9) The most significant bit is printed on top, and the least significant at the bottom.
