GS Q 0   [obsolete command]

xL, xH specifies (xL + xH × 256) dots in horizontal direction for the bit image.

yL, yH specifies (yL + yH × 256) bytes in vertical direction for the bit image.

d specifies the bit image data (column format).

k indicates the number of the bit image data. k is an explanation parameter; therefore, it does not need to be transmitted.

Selecting a color for printing is possible.

Selecting a size in dot units is possible.

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. 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.

This command cannot be included in a macro definition. Do not use this command when defining a macro.

After printing a variable vertical bit-image, normal data processing is started. The print postion is moved to left side of the printable area. Also, the printer is in the status "Beginning of the line".

Relationship between bit-image data and printing result is as follows:
