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. HP LaserJet 4 Printer Several new PCL features were added to the PCL 5 language with the release of the HP LaserJet 4 printer. These new features are summarized in Table 2-3. Most of these features are described in the revised PCL 5 Printer Language Technical Reference Manual (part number 5961-0509). (This revised technical reference manual is supplied as part of the Technical Reference Documentation Package which can be obtained by ordering part number 5961-0601.) In addition, there are some additional differences for the HP LaserJet 4 printer that are not covered in the technical reference manual but are described below. Note The HP LaserJet 4M printer, in addition to PCL, contains PostScript and a LocalTalk I/O for printing in the Macintosh environment. PCL operation and the PCL internal fonts for this printer are identical to the HP LaserJet 4 printer. Thus, for PCL information for the HP LaserJet 4M printer, refer to the HP LaserJet 4 printer features. 2-4 Printer-Specific Differences ENWW
