Paper roll Bit-image commands GS Q 0
Ver. 10.01 p. 289
[Recommended Functions]
This command is supported only by some printer models and may not be supported by future models.
It is recommended to use graphics function (GS ( L GS 8 L: <Function 50> and <Function 113>). The
graphics functions are better than GS Q 0 for the following reasons:
Selecting a color for printing is possible.
Selecting a size in dot units is possible.
[Notes]
In standard mode, this command is effective only when data is not in the print buffer and the printer is at
the beginning of the line.
This command processes
k
bytes data of
d1...dk
as a bit image data. Image data (
d
) specifies a bit printed
to 1 and not printed to 0.
If a variable vertical bit image that exceeds the print area for a line is specified, the excess image data is
ignored.
The scales for width and height of NV bit images are specified by
m
. Therefore, in page mode with 90° or
270° clockwise-rotated NV bit image, the printer applies print area and dot density from [width: direction
of paper feed, height: perpendicular to direction of paper feed].
Character size and all print modes such as emphasize, underline, 90° clockwise rotation, or upside-down,
do not affect printing of a variable vertical size bit image data.
This command feeds paper for the amount needed for printing a variable vertical bit image regardless of
the paper feed setting set by paper feed setting commands.
Do not use this command during macro execution because the command cannot be included in a macro.
After printing a variable vertical bit-image, normal data processing is started.
The print position is set to the left of the print area. The printer is at the beginning of a line and data is not
in the print buffer.
