Graphics Commands
In 80 mm printers, the line length is 72 bytes and in 112 mm printers it is 104 bytes.
Prints a black & white Windows bitmap (BMP-file) at the specified X-Y position. The bit-map
must be a complete uncompressed Windows bitmap where the data starts with BM. Max size
is limited to the free RAM printed on the self-test printout.
.
After the bitmap has been printed, the cursor will return to the X-position that it had before the
bitmap command was issued.
Selecting horizontal mode (with <ESC>o<0>) prints the image in portrait orientation, while
selecting the vertical mode (with <ESC>o<1>) prints the image in landscape orientation.
Sends one line of dot data. This command is used to build images, one dot line at a time by the
printer driver and should not be combined with text commands.

data Bitmap data.
Note • The Y print-position and horizontal/vertical orientation only works if fixed page
length is used.
ESC s n1 data

1B 73 n1 Data Hex
27 115 n1 Data Decimal
n Determines the number of bytes. Range: 1-255.
<data> 1 – x bytes, where x is the printhead width in bytes. The printhead width
is in the spec. of the printer.
Example • 80 mm printers use 72 bytes
Example • 112 mm printers use 104 bytes
Caution • Always send the No. of bytes that you specify!
If more than the specified No. of bytes are received, the rest of the bytes will be interpreted
as text or commands. This can cause any kind of problems in the printer as graphics data
can contain any hex value. If you specify less data then the actual printhead width, the
printer will fill the rest of the dot line with spaces.
