I managed to chane the opacity/greyscale of the typewriter font.
(1) is there a way to reset to the default all of the color/options in Abobe Acrobat 7
(2) a way to reset the font to appear black as before
I found a related mention about a Adobe Technote #320120 on the subject, but cannot find the technote on the Adobe site, any way of finding this.
"Re: Typewriter font prints in greyscale not black
We have a similar problem on one PC(at least I think it is similar). Every few months something changes, and the typewriter text becomes so light it is almost illegible. Using Adobe technote 320120, I alter the registry and it fixed the problem for awhile. "
