Paper roll Bit-image commands GS v 0
Ver. 10.01 p. 294
Data (
d
) specifies a bit printed to 1 and not printed to 0.
If a raster bit image exceeds one line, the excess data is not printed.
The scales for width and height of raster bit images are specified by
m
. Therefore, in page mode with 90°
or 270° clockwise-rotated raster bit image, the printer apply print area and dot density from [width:
direction of paper feed, height: perpendicular to direction of paper feed].
The raster bit image is not affected by print modes (emphasized, double-strike, underline, character size,
white/black reverse printing, upside-down printing, or 90° clockwise-rotated).
This command feeds as much paper as is required to print the raster bit image, regardless of the line
spacing specified by ESC 2 or ESC 3.
If this command is processed while a macro is being defined, the printer cancels macro definition, clears
the definition, and prints a raster bit image.
After printing a raster bit image, the printer processes normal data.
The print position is set to the left of the print area. Printer is in the beginning of a line and data is not in
the print buffer.
The bit image is printed in the default dot density (dot density of vertical and horizontal direction in
normal mode) defined by GS L <Function 49>.
The relationship between bit image data and the print result is as follows:
