I recently found the snipping tool in my accessories on Windows 7. I put it on my tasklbar and started using it. It allows you to clip anything you can see off of your screen. The resulting image can be saved as HTML, jpeg, gif of png. I found the clarity every bit as good as the pre-captured screen.
PDF995 is the software that I have installed that lets me print anything and save it as a pdf. I use it to store invoices, make labels etc. It works fine but I have noticed that there is a clarity differential between the screen that is captured as a pdf and the original screen.
Compared side by side I see an appreciable difference in clarity with the MS Snipping tool over PDF995. MS Snipping tool comes with Windows 7 and is in a rationalized thought thusly free. PDF995 cost me $10.00. Free is good and in this case it is not “gooder” it is better.
