The following example prints a Group 4 image file that is 256 bits wide and 9,645 bytes

long:

 

ESC*b1002M

Set Raster Compression to Group 4

ESC*r256S

Define width of image in input bits

ESC*r1A

Start Raster Graphics at current position

ESC*b9645W

9,645 bytes of a Group 4 image

...[Group 4 image data]...

 

ESC*rB

End Raster Graphics

All lines of data must be the same length. If they are not, zeroes (0) must be added to attain the same length.

Note: If the uncompressed image extends beyond the logical page dimensions or beyond the raster width specified in the Raster Width command (ESC*r#S), the image is clipped at print time.

Additional Compression Modes

When the compression mode is 1008 (Lexmark Adaptive), TIFF word and double- word can be printed using compression scan modes 254 and 255 respectively. This compression method sends a raster image as a block of raster data.
