PCL Rectangular 
Area Fill Graphics 
Introduction 
The PCL language includes commands for filling or shading 
rectangular areas on the page with pre-defined patterns, and 
allows creation and use of user-defined patterns. Pre-defined 
patterns include eight shading patterns and six cross-hatch 
patterns.
NoteUser-defined patterns are not supported on all LaserJet family 
printers. Refer to the “PCL Feature Support Matrix” in the PCL 5 
Comparison Guide.
The first step in filling...

3Specify width of rectangle (Horizontal Rectangle Size Command - 
Decipoints=E
C*c#H, or PCL Units=E
C*c#A).
4Specify height of rectangle (Vertical Rectangle Size Command - 
Decipoints=
E
C*c#V, or PCL Units=E
C*c#B).
5Select specific shade, cross-hatch, or user-defined pattern 
(Pattern ID Command -

ENHorizontal Rectangle Size (Decipoints) Command 14-3
Horizontal Rectangle Size (Decipoints) Command 
This Horizontal Rectangle Size command specifies the rectangle 
width in decipoints.
E
C * c # H 
#  =Number of decipoints (1/720 inch)
Default =0
Range =0 - 32767 (valid to 4 decimal places)
The printer converts the specified width to printer dots by rounding 
up to an integral number of dots. For example, 5 decipoints, which 
corresponds to 2.08 dots in 300 dpi mode, is converted to 3 dots.

Vertical Rectangle Size (Decipoints) Command 
This Vertical Rectangle Size command specifies the rectangle height 
in decipoints.
E
C * c # V
#  =Number of decipoints (1/720 inch) 
Default =0
Range =0 - 32767 valid to 4 decimal places
The printer converts the specified width to printer dots by rounding 
up to an integral number of dots. For example, 5 decipoints, which 
corresponds to 2.08 dots in 300 dpi mode, is converted to 3 dots.

ENPattern ID (Area Fill ID) Command 14-5
Pattern ID (Area Fill ID) Command 
The Pattern ID command (formerly called Area Fill ID) identifies the 
specific shading, cross-hatch, or user-defined pattern (see Figure 
14-2) to be used when filling a rectangular area.
E
C * c # G
Default =0 (no pattern)
Range =0 - 32767 (values outside the range are ignored)
The value field (#) identifies the level of shading, the cross-hatch 
pattern, or the user-defined pattern.
There are eight HP defined shading patterns...

14-6   PCL Rectangular Area Fill GraphicsEN
There are six HP defined cross-hatch patterns. To specify a cross- 
hatch pattern type, use a value between 1 and 6 to select a pattern 
as shown in Figure 14-2.
For user-defined patterns, this command, sent prior to downloading 
a user-defined pattern, assigns an ID pattern number to the 
downloaded pattern. (For more information, see “User-defined 
Pattern Graphics,” in Chapter 13.)
NoteThis command works in conjunction with the Fill Rectangular Area 
Command...

ENFill Rectangular Area Command 14-9
Fill Rectangular Area Command 
This command fills (prints) a rectangular area of the specified width 
and height with the specified area fill.
E
C * c # P
#  =0 - Black fill (rule)
1 - Erase (white) fill
2 - Shaded fill
3 - Cross-hatch fill
4 - User-defined pattern fill
5 - Current pattern fill 
Default =0
Range =0 - 5 (values outside the range are ignored)
Black fill — fills the rectangular area with black fill. 
White fill — erases any fill in the rectangular area...

14-10   PCL Rectangular Area Fill GraphicsEN
The upper left corner of the rectangular area is located at the 
cursor position when printing a rectangular area. After printing the 
rectangular area the cursor is returned to the upper left corner; the 
cursor position does not change positions as a result of printing a 
rectangular area.
Rectangular areas are independent of the text area and perforation 
skip mode; these boundaries are ignored (rectangles are not clipped 
at these boundaries). Addressable...
