[Function] Printing of raster bit image
[Code] <1D>H<76>H<30>H<m><xL><xH><yL><yH> [<d>] k
[Range] 0 m 3, 48 m 51, 0 xL 255, 0 xH 255,
0 yL 255, 0 yH 8, 0 d 255,
k = (xL + xH × 256) × (yL + yH × 256), however, k ≠ 0
[Outline] Prints raster bit images in mode “m”.
• xL, xH specify the number of data in horizontal direction of the bit image to (xL +
xH × 256) bytes.
• yL, yH specify the number of data in vertical direction of the bit image to (yL + yH ×
256) bytes.
[Caution] • In STANDARD MODE, this command is valid only when there is no print data in the
print buffer.
• Any of the print modes (character size, emphasis, double strike, inverting,
underlining, back-to-white reversing, etc.) does not affect the raster bit image.
• If the print area specified by GS L and GS W is narrower than a minimum width,
the print area for that line only is extended to the minimum width. The minimum
width is one dot in NORMAL MODE (m = 0, 48) and DOUBLE HEIGHT MODE (m = 2,
50), and 2 dots in DOUBLE WIDTH MODE (m = 1, 49) and QUADRUPLE SIZE MODE
(m = 3, 51).
• Any part of data that is out of the print area is only read and discarded in units of
dot.
• The print start position can arbitrarily be specified with HT (horizontal tab), ESC $
(specifying absolute position), ESC \ (specifying relative positions), and GS L (setting
left margins). Note that if the print start position is not a multiple of 8, the printing
speed may decrease.
• The setting of ESC a (aligning characters) are also valid for the raster bit image.
• If this command is executed during macro definition, the macro definition is
suspended, and the processing of the command starts. The macro is left undefined.
•“d” denotes defined data. Dots to be printed are specified as “1”, and those not to
be printed as “0”.
