ENIntroduction 15-3 The final data reduction technique provided by the raster area 
involves the printer’s ability to fill in trailing zeros to the edge of the 
raster area. Any zeros following the last “1“ in the raster row to the 
edge of the picture area need not be sent. The printer automatically 
fills them. This technique eliminates the need to transmit raster data 
rows that are all the same length, as required in a raster image which 
does not use the raster area feature.
The raster area...

Raster Graphics Command Sequence 
PCL raster commands include: Start Raster Graphics and End Raster 
Graphics commands, Transfer Raster Data by Row, Raster 
Compression, Raster Presentation, Raster Resolution, Raster Height 
and Raster Width (which define the raster area), and Raster Y Offset 
commands. The normal sequence of execution for these commands 
is shown below:
The emphasis in the previous command sequence is that the Raster 
Presentation Mode, Raster Resolution, Raster...

ENRaster Graphics Command Sequence 15-5 Raster Presentation, Raster Resolution, Raster Height, Raster Width, 
and Raster Compression are all true modes. Once specified, the 
printer remains in that mode unless explicitly changed by issuing 
the command again, or reset to default values by a soft reset, self 
test, font printout, or power cycle.
NoteOnly raster data appearing within the intersection of the logical 
page, the printable area, the raster width, and height is printed. 
If raster width and/or...

Raster Graphics Resolution Command 
Raster graphics can be printed at various resolutions. This command 
designates the resolution of subsequent raster data transfers in 
dots-per inch.
E
C * t # R 
#  =   75 - 75 dots-per-inch
100 - 100 dots-per-inch
150 - 150 dots-per-inch
200 - 200 dots-per-inch
1
300 - 300 dots-per-inch
600 - 600 dots-per-inch
Default =75
Range =75, 100, 150, 200, 300, 600
This command must be sent prior to the start graphics command. The 
factory default...

ENRaster Graphics Resolution Command 15-7 Figure 15-3 Raster Graphics Expansion - at 300 dpi
NoteRectangular area fills and character data are not affected by changes 
in resolution. Rectangular Area fills and character data always print at 
the maximum resolution, regardless of the resolution setting.
When configured for 600 dpi resolution, the printer automatically 
expands raster graphics transferred at resolutions less than 600 
dots-per-inch to 600 dots-per-inch during printing.  illustrates how a...

Raster Graphics Presentation Mode Command 
The Raster Graphics Presentation command specifies the orientation 
of the raster image on the logical page.
E
C * r # F 
#  =0 - Raster image prints in orientation of logical page
3 - Raster image prints along the width of the physical 
page 
Default =3
Range =0, 3
A value of 0 indicates that a raster row ‘will be printed in the positive 
X-direction of the PCL coordinate system. (The print direction 
translates the PCL coordinate...

ENRaster Height Command 15-11
Raster Height Command 
The Raster Height command specifies the height in raster rows of the 
raster area. Height is the direction perpendicular to the direction that 
raster rows are laid down, hence, height is subject to the current 
raster presentation mode and print direction (see Figure 15-7).
E
C * r # T
#  = Height in raster rows 
Default =N/A
Range =0 to (logical page length – current Y-position of the
0,cursor)

* Greater values default to (logical page length –...

Upon receiving an End Raster Graphics (E
C*rC) command, the 
cursor position is set to the left graphics margin of the next raster row 
after the raster height boundary.
