Graphic commands examples
For this 24-bit graphic pattern we have eight
bit-columns, each with a height of 3 bytes
(24 bits). The printer must, after the command
is stated, receive the 1
st , 2 nd and 3 rd bytes of
the first bit-column, than the 1 st , 2 nd and 3 rd
bytes of the second bit-column and so on, until
the last
The command sequence to print this graphic pattern would be (numbers in decimal):
ESC * ! 8 0 1 1 1 2 2 2 4 4 4 8 8 8 16 16 16 32 32 32 64 64 64 128 128 128
Where you have 8 + 0 * 256 = 8 bit-columns to be filled, each with 3 bytes that will give us a
total of 24 bytes to be sent (excluding the command sequence).

24-bit graphics
For this 8-bit graphic pattern we have eight bit-
columns, each with a height of 1 byte (8 bits).
The printer must, after the command is stated,
receive the byte for the first bit-column, than the
byte for the second bit-column and so on, until
the last bit-column is filled. The resolution is
lower but needs less bytes to be sent
The command sequence to print this graphic pattern would be (numbers in decimal):
ESC K 8 0 1 2 4 8 16 32 64 128
Where you have 8 + 0 * 256 = 8 bit-columns to be filled, each with 1 byte that will give us a
total of 8 bytes to be sent (excluding the command sequence).
