Right click on the Screenshot Captor icon in the tray and choose Explore at Screenshot Directory, then go up one level and you should see the .ini file.

Works fine on my Win 8 machine with a Lexmark x7675 AOI.  After you click File, Print Screenshot, click the Print Setup... button in the middle and you can select a printer and settings in the normal dialog.

Happens to me often.  I find it difficult to resist downloading utilities that have been recommended by reasonable people, or that address an issue I've seen (even peripherally), or that just sound neat.  Or ones that do the same thing I already have a utility for but maybe have an interesting feature.  And since the landscape changes constantly I sometimes revisit topics that I've spent too much time on already (how many times have I looked at text editors?).  Most of it gets installed and tried out and I get excited about it, but then something else comes along...

Happens less often with purchased products, but still happens.  I can buy software based on an awesome demo but later find the workflow doesn't fit, or buy a product and the developers take it somewhere I don't like as much.

I think anyone who's willing to take a chance on finding a better way should see this happen now and again.

(btw, anyone want a copy of UltraEdit with lifetime updates?)
