Why the font prints encrypted when I use the visio 2007 program?
The text may appear to be gobbledygook, not encrypted though.
1. menu Tools -> Options
in the View display options section, check the value of "Greek text
under", it's nothing to do with Greek at all but a print size below
which the display will just show an approximation of the text, set it
to 0, see what that does.
2. Rather than print try to save as an image file, GIF or EMF or PNG
would be ideal. Does the text still look like rubbish?
