In run-length encoding compression mode, the data to be printed is always
transferred in the format (counter) + (data), where counter represents one byte of
information.
If 0  counter  127, then the data following the counter is non-compressed data, and the
length of the compressed data is (counter)+1 bytes.
If 128 counter 255, then the data following the counter will be one byte of
compressed data, . This single compressed byte of data is thereafter to be repeated
257-(counter) times..
3) This function also increments the X printing position relative to the current X printing
position by the amount: (256 x nH + nL) x h/3600 x 25.4mm.
If this command specifies an X position in the non-printable area (right margin), the right
margin position is automatically reset to the X value of the new printing position.
4) If image data is designated for a non-printable area, then the image data designated for that
area is ignored.
