ENPattern Transparency for Rectangular Area Fill 14-11
Pattern Transparency for Rectangular Area Fill 
Pattern transparency, described in Chapter 13, under “Pattern 
Transparency Mode Command,” affects how a pattern is applied 
to the rectangular fill area. Rectangular areas are special case 
images for transparency mode. The pattern and pattern type 
are selected by the Pattern ID command (
E
C*c#G) and the Fill 
Rectangular Area 
(E
C*c#P) command (described earlier in this 
chapter).

Rectangular Area Fill Examples 
This section shows example usage of area fill commands to print 
pre-defined patterns as well as user-defined patterns.
Pre-defined Pattern Examples 
Solid Fill (Black/White) 
To print a 900 by 1500 Unit black rule (3 inches by 5 inches at 300 
units-per-inch), then white fill a small area inside the black rectangle, 
perform the following steps.
11. Position the cursor:
E
C*p300x400Y 
This moves the cursor to PCL Unit position (300,...

66. Specify the width and height for the smaller white fill 
rectangular area:

C*c300a600B
77. Select the white fill and print.

Shaded Fill 
To print a 900 by 1500 Unit 25% shaded rectangle (3 inches by 5 
inches at 300 units-per-inch), perform the following steps.
1Position the cursor:
E
C*p300x400Y 
This moves the cursor to PCL Unit position (300, 400) within 
the PCL coordinate system.
2Specify the width of the...

This sets the rectangle to 1500 PCL Units (5 inches at 300 
units-per-inch).
4Specify the Pattern ID:
E
C*c25G 
This sets the Pattern ID to 25.

Cross-hatch Fill 
To print a 900 by 1500 Unit rectangular area (3 inches by 5 inches 
at 300 units-per-inch), filled with a horizontal cross-hatch pattern, 
perform the following steps:
1. Position the cursor:
E
C*p300x400Y 
Moves the cursor to PCL Unit position (300,400) within the PCL 
coordinate systems.
2. Specify the width of the rectangle:
E
C*c900A 
Sets the rectangle width to 900 PCL Units (3 inches at 300 
units-per-inch).
3. Specify the height of the...

User-defined Pattern Example  
This example shows how to print a user-defined pattern which has 
already been downloaded to the printer. For this example we will print 
the pattern of triangles which was downloaded in the example in 
Chapter 13, under “User-Defined Pattern Command.”
The following commands define a 600 PCL Unit square rectangular 
area, select ID number 3, and print the...

Raster Graphics 
Introduction 
A raster image is an image composed of dots. Pictures in 
newspapers or on television screens (also, a page printed by 
this printer) are examples of raster images. The PCL language 
includes commands for printing raster graphic images. These 
commands enable the LaserJet printer to receive binary data 
and print it as a raster image.
The binary data used to create a raster image is divided into dot 
rows: a row describes a one-dot-high strip of the...

several binary data compression methods, and additional reduction 
techniques associated with the raster area feature (see Figure 15-2).
Figure 15-2 Raster Area
Data compression methods include: run-length encoding, tagged 
image file format (TIFF), delta row, and adaptive compression. These 
techniques are described in detail later in this section, under the Set 
Compression Method command.
In addition to the compression methods, the raster area feature 
provides some other...
