Color Raster Images The suggested method for printing color images is by using 24-bit, direct color pixels with delta row compression. The 24-bit, direct color is specified using the Configure Image Data command. Delta row compression is recommended over run length, or TIFF pack bits since 24-bit, direct color uses three bytes per pixel so there is little redundancy from one byte to the next. Delta row compression exploits the redundancy from row to row, and therefore yields better compression than any other supported PCL compression mode. Asian Font Support The following commands are supported especially for Asian font printing: • Character Text Path Direction • Text Parsing Method • 2-byte characters • HP-GL/2 Label allows 2-byte characters. Media Handling The HP Color LaserJet 4500 printer has two standard paper trays and one optional tray. They are accessed as follows: Tray Tray 1 Tray 2 Tray 3 Description Multi-purpose paper tray. This is the upper-most paper input tray and has a retractable paper support. Lowest standard paper tray Optional 500-sheet input paper tray. When installed, it is the bottom tray. Command ?&l4H ?&l1H ?&l5H Paper can be selected by requesting a media type using the Paper Type command (?&n#Wdpapertype, where # is the number of characters in "papertype". For example, the command to select Color paper is ?&n6WdColor. To select "Prepunched" the ?&n11WdPrepunched command would be used. 2-112 Printer-Specific Differences ENWW
