Print downloaded bit image
ASCII GS / m
Hexadecimal 1D 2F m
Decimal 29 47 m
Value and range of m:
This command is used to print a previously stored
monochrome or color logo from printer memory on the
receipt station. The logo is identified as the one indicated
by the most recent select current logo command or 0 if a
select current logo command has not yet been given.
Parameter m is interpreted as follows:
Value of m Print mode Vertical DPI Horizontal DPI
0 Normal 203 203
1 Double Wide 203 101
2 Double High 101 203
3 Quadruple 101 101
The indexed downloaded bit image from RAM or flash
will be printed on the receipt station at a size specified by
m. If the bit image is a monochrome one, it is printed in
the current color; otherwise it is printed as a 2-color
image. If doubling or quadrupling exceeds the print paper
width maximums (576 or 640 with 82.5-mm paper) the
left side of the image is printed and the bits to the right of
the maximum column are discarded. If the available width
is greater than the bit image, its printing will adhere to any
currently set right, left, or center justification. This
command is ignored if the index refers to an undefined
logo/ bit image.
Print raster monochrome graphics (ColorPOS™)
ASCII GS 0x82 n1…..n72 (576 dots) for 80 mm paper, or n80 (640 dots) for 82.5 mm paper
Hexadecimal 1D 82 n1…..n72 (576 dots) for 80 mm paper, or n80 (640 dots) for 82.5 mm paper
Decimal 29 130 n1…..n72 (576 dots) for 80 mm paper, or n80 (640 dots) for 82.5 mm paper
Value and range of n: n1 to n72/n80 corresponds to
one dot row data for a thermal
receipt printer.
Each bit defines whether or not a dot of the current color
will be printed. This command is used for printing a
monochrome graphic in real-time. Offsets, page and any
other modes or overlays, including watermark do
not apply
and are overridden by this command. A complete
rendering of the intended final image should have been

done by the application before sending the dot rows.
If 2-color paper is indicated by the set paper type
command, then the raster will be printed in the color that
is defined by the set current color command.
