Digital BW, The Print

a. I am  still having trouble reading clayton jones' article on ps cs
on an epson 2200
when I open an bw image it often asks me what working space i want to
be in

when I go front end , I go to ps image/mode/grayscale I dicard
color as asked I then go to edit and assign profile I get three options
1. dont color manage
2. working gray dot 20% and
3. profile with a pull down window with option for 15 dot 20 etc as
well as gray gamma 1.8 2.2
I dont see these option in his article

any help with which choice of the  above three option I select?


I think I am ok when I go to print with preview and select "dont
color manage"
