HP L 5 manual Simple Color Mode, Simple Color Command, ? *r#U, Default Range

Simple Color Mode

The Simple Color command (?*r#U) specifies color selection from a fixed palette. RGB or CMY raster data must be sent by plane (?*b#V) as well as by row (?*b#W). The last plane in each row is sent using the ?*b#W command; all other planes are sent using the ?*b#V command. In Simple Color mode, the pixel encoding mode is always indexed planar.

Simple Color Command

The Simple Color command creates a fixed-size palette, whose color specification cannot be modified.

?*r#U
# = –3	- 3 planes, device CMY palette
1	-	Single plane K (Black) palette
3	-	3 planes, device RGB palette
Default	=	1
Range	=	–3, 1, 3

This command destroys the active palette and creates a new palette, which becomes the active palette. When the Simple Color mode is active, PCL and HP-GL/2 commands that modify the palette are locked out (NP, PC, ?*v#A, ?*v#B, ?*v#C, ?*v#I). When a Simple Color palette is popped from the stack (?*p#P), it cannot be modified, and the pixel encoding mode reverts to indexed planar.

•A value field of 1 creates a 2-entry Black-and-White default palette.

•A value field of 3 creates an 8-entry Device RGB palette (compatible with a PCL Imaging Mode palette, but not an HP-GL/2 default (IN) palette).

•A value field of –3creates an 8-entry palette in Device CMY color space.
