This is something I am not able to explain -- when I do a screen capture of an UI element on my Windows box (Alt-PrintScreen), paste that on a Visio diagram and then do a resize (mostly reduce size) then the resulting picture comes our real lousy on printer.
However, if I paste the image on a WORD document, do a resize there and then copy the resized image to Visio then the quality is much better.
So, I have found asolution to my problem. Just don't know why it happens the way it happens.
