HP LaserJet IIIP Printer
Several new PCL features were added to the PCL 5 language with the 
release of the HP LaserJet IIIP printer. These new features are 
summarized in Table 2-2. One new feature listed here is adaptive 
compression (method 5) for the Raster Compression Mode 
command. In addition to compressing data for transmission, if certain 
rules are followed (discussed below), the HP LaserJet IIIP printer will 
store adaptive compressed data in compressed format and only 
decompress it when required for printing. There are certain 
requirements which must be met for this data to be stored in 
compressed format. These requirements are discussed following 
Table 2-2.
