7 Color Vector Graphics (HP-GL/2)

Introduction

The process involved in using HP-GL/2 with the HP Color LaserJet family or DeskJet 1200C and 1600C color printers is nearly identical with using HP-GL/2 on other color printers or plotters. However, these two color printers add a few HP-GL/2 commands and expand the functionality of some existing commands. This chapter describes these commands and other pertinent points to keep in mind when using HP-GL/2 with these color printers.

The HP-GL/2 commands explained in this chapter include the following: The Merge Control (MC) command, which functions in a similar way to the PCL logical operation command. The Pen Color (PC) command, which modifies palette colors, the Number of Pens

(NP) command, which changes the palette size, the Pixel Placement (PP) command, which determines how pixels are rendered in HP-GL/2 polygons, and the Color Range (CR) command, which sets the range for specifying relative color data (the CR command is not supported by the HP Color LaserJet 4500 or 8500 printers).

In general, when using HP-GL/2 on the HP Color LaserJet family and DeskJet 1200C and 1600C color printers, keep in mind that:

•Palette information stays the same when switching between PCL 5 and HP-GL/2.

•The HP-GL/2 Initialize (IN) command sets the palette to the default eight-pen palette, and also resets the ROP code (see the MC command section later in this chapter) and the pixel placement command.

•As with color plotters, to specify a particular color, you use the SP (Select Pen) command.

If you are not familiar with using HP-GL/2, see the PCL 5 Printer Language Technical Reference Manual.
