HP L 5 manual Black-and-White Mode Default, Simple Color Mode

2 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.
