This command differs from the 8 Bit Graphics command described above by reducing the number of bits (bytes) that
have to be sent to the printer. This allows for faster data transfer between the host computer and the printer.
Graphic String Component Function
height
(# of lines)
An eight bit value representing the number of dot-lines contained in the following data set
width
(# of bytes in each line)
An eight bit value representing the number of bytes to be contained in each dot-line of the following
data set
An eight bit value which describes how the following data will be processed
For Signed
Values
{127 ≥ Counter ≥ 0} Process the next (Counter + 1) bytes of data as 8 bit
graphics.
{0 > Counter ≥ -128} Repeat the next single byte of data ((-Counter) + 1) times.
counter
r (# of lines)
For Unsigned
Values
{127 ≥ Counter ≥ 0} Process the next (Counter+1) bytes of data as 8 bit graphics
{128 ≥ Counter ≤ 255} Repeat the next Singe byte of data, (( 256 – Counter)+1)
times
Example: Compressed graphic
The following graphics data is to be printed:
