Using Color Modes
Introduction
The PCL printer language has four color modes:
• Black-and-White
•Simple Color
• PCL Imaging
• HP-GL/2 Imaging
PCL allows you to use any mode or combination of modes to
accomplish your printing objectives most efficiently.
All four of the color modes create a palette. The palette for each mode
is discussed in the section describing that mode, and also in
Chapter 3 (“Using Palettes”).
Black-and-White Mode (Default)
Black-and-White Mode is the default color mode. PCL devices power
up in this mode and revert back to it whenever the printer receives an
?E reset. Black-and-White mode is also selectable using the Simple
Color command (
?*r1U). This mode creates an unmodifiable, default
2-pen palette, with white at index 0 and black at index 1 (compatible
with existing monochrome PCL 5 printers).
Simple Color Mode
Simple Color Mode, entered by the Simple Color command (?*r#U),
creates a fixed-size, fixed-color, unmodifiable palette. Depending on
the value field,
?*r#U can create a 2-pen Black-and-White palette,
an 8-pen RGB palette, or an 8-pen CMY palette. When using the
Simple Color mode, the pixel encoding mode is always indexed
planar.
