HP PCL/PJL reference - PCL 5 Comparison Guide

2-114 Printer-Specific Differences ENWW
New Paper Sizes
The HP Color LaserJet 4500 printer supports ISO A5 and B5 paper
sizes.
Forms Support
Forms are supported by the use of PCL macros which also include
support for HP-GL/2 commands.
Alphanumeric ID Command
The HP Color LaserJet 4500 printer supports all the options of the
Alphanumeric ID command. However, since the HP Color
LaserJet 4500 does not support a disk drive, associations can only be
made with non-disk-based fonts or macros. For more information on
the Alphanumeric ID command, see page 2-79.
Color Space Support
The supported color spaces are Standard RGB (sRGB), Device RGB,
and Device CMY. Standard RGB replaces Colorimetric RGB (cRGB).
All other color spaces supported in the HP Color LaserJet or Color
LaserJet 5 are not supported in the HP Color LaserJet 4500 printers.
Changes to PCL 5 Color Commands
The focus of the printer’s color support is on WYSIWYG color usage
and a simplified usage model. A number of PCL 5 color commands
introduced in the HP Color LaserJet and supported in the Color
LaserJet 5 printer have been made obsolete as a direct result of using
Standard RGB color to achieve WYSIWYG color. Furthermore,
several commands have been modified to match the predicted use of
the HP Color LaserJet 4500 printer.
