Raster Graphics Adaptive Compression (IIIP)
Adaptive compression was added to the PCL language with the
introduction of the HP LaserJet IIIP printer. Adaptive compression (or
method 5 as it is referred to) is a method for compressing raster data
using the raster Set Compression Method command (parameter
value 5). (Refer to the Set Compression Method command in the
PCL 5 Printer Language Technical Reference manual for detailed
information on using this compression technique.) Also, refer to
Chapter 5 in this document, “Raster Graphics Adaptive Compression
(Method 5)” for additional information.
