2.2.

Using PCL Color Mode - Set PCL Color Setting 

Command 

ESC*v#W (27)(42)(118)#(87)  <1Bh><2Ah><76h>#<57h> 

# = 6, 18 
# stands for the number of bytes of data that follow this command. 

This command sets the palette size and transformation between the entered value and device-specific value. 

This command has two types of format, 

short format

 and

 long format

.    Here are the formats for the PCL 

color setting. 

1) Short 

Format 

 MSB 

LSB 

0 - 1 

Format (0) 

Encoding mode 

2 - 3 

Bits / index 

Bits / value #1 

4 - 5 

Bits / value #2 

Bits / value #3 

♣

Format 

This value must be 0. 

♣

Encoding mode 



This value defines how to send the raster image data. 



The value can be from 0 to 3 only, other values are ignored. 

Encoding Mode   

0 

Send Index No by Plane * 

1 

Send Index No by Pixel 

2 

Send Direct Value by Plane 

3 

Send Direct Value by Pixel 

* = default 

Send Index No by Plane (= 0 default) 



This mode assigns the Index No. to the Plane, then sends it. 



The necessary number for the Plane is determined depending on the number of bits/index.    1 (one) plane 
should be needed per 1 (one) bit/index.    For instance, 4 planes are needed for 4 bits/index. 



Bits/index must be 1, 2, 4, 5, 6, 7, 8. 



This mode sends the plane data except the last one using the 

Send Raster Data by Plane

 command 

(

ESC*b#V

).   



This mode also sends the last plane data using the 

Send Raster Data

 command (

ESC*b#W

). 

(i.e. 4 bits/index) 

ESC*b#V d1, d1, d1,
