HP PCL/PJL reference (PCL 5 Color) - Technical Reference Manual

EN Using Color Modes (Color LaserJet, 5, 5M, DeskJet) B-3
HP-GL/2 Imaging Mode
In HP-GL/2, the Initialize (IN) command starts color imaging and
performs the following:
• Sets the pixel encoding mode to index by plane.
• Sets bits per index to 3.
• Creates an 8-pen palette that is reprogrammable in either PCL
or HP-GL/2 contexts (see Appendix C, “Using Palettes,” for
more information).
Although default HP-GL/2 palettes are different than default PCL
palettes, an HP-GL/2 palette is modifiable in either PCL or HP-GL/2
(using the Assign Color Index [
?*v#I] or Pen Color [PC] commands,
respectively). Likewise, a PCL palette created by the Configure Image
Data command (
?*v#W) is modifiable in both PCL and HP-GL/2
using the same commands.
The active palette is always transferred between HP-GL/2 and PCL
contexts. Since only one palette at a time can be active, a new palette
created in either context overwrites the current palette.
