color to grayscale

[suvigy]

Hi all!

We are developing a pcl application that uses colors for text, and for filling rectangle. But for a new demand we have to rewrite the whole program so that it should use grayscaling. What's the simpliest way to do this? Printer prints the colors as black. And we tried the ESC & b 1 M command. But no effect.
is there any command that switches between color and grayscale modes and works? I hope, we dont need to write own palette.
Thnx for the answers in advanve
George

You should be able to specify a shading level...

<esc>*c15G which is a 15% shade

For a rectangle

<esc>*c500a500b2P

The 2P specifies a shaded fill.

For text <esc>*v2T MY SHADED TEXT <esc>*v0T

The 2T specifies shaded text and the 0T black text.

Both use the % parameter at the top.
