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

0Send Index No by Plane *

1Send Index No by Pixel

2Send Direct Value by Plane

3Send 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, d1, d1 ...→ Plane 1		1st raster
ESC*b#V d2, d2, d2, d2, d2 ...→ Plane 2
ESC*b#V d3, d3, d3, d3, d3 ...→ Plane 3
ESC*b#W d4, d4, d4, d4, d4 ...→ Plane 4
ESC*b#V d1, d1, d1, d1, d1	...→ Plane 1	2nd raster
ESC*b#V d2, d2, d2, d2, d2	...→ Plane 2
