HP (Hewlett-Packard) PCL Printer User Manual


 
2-6 Using Color Modes EN
The bytes are ordered as follows and are unsigned bytes:
Invalid configurations of the CID command are ignored and the data
discarded. A minus or a plus sign in the value field (-6 or 6) is ignored
The data fields in the command, bytes zero to five, must contain
byte-aligned binary data, not ASCII data.
Byte 0 (Color Space)
This byte specifies the color space. The range of values is 0 through
2. All other values are ignored.
Color space 2, sRGB, was the designation for Colorimetric RGB in
the Color LaserJet and Color LaserJet 5 printers. The value 2 is used
to represent sRGB since it is analogous to a standardized
Colorimetric RGB and the intent of the two color spaces is the same.
