2.2. Using PCL Color Mode - Set PCL Color Setting 2001/10/02 Command ESC*v#W (27)(42)(118)#(87) # # = 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 1 2 3 Send Index No by Plane * Send Index No by Pixel Send Direct Value by Plane 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).
