Interesting results. I used to use Times New Roman as my default but have changed to using a sans serif font as I read a lot more on the screen and sans serif fonts are easier to read on a screen. I personally find Calibri a particularly ugly font.

The software you mention is only any good if you are

a) Using Windows

b) Using Internet Explorer

As I use neither, it is useless to me.

There are ways you can reduce the amount of printing from the web without resorting to fancy software and it does not depend on have a particular operating system or browser.

Use print preview to check the way the pages will look and only print those pages you need.

If you find from print preview that there is a great deal of extraneous material which is not needed in the printout, then copy and paste the material you do need into a word processor and print from there. If it is an image you need, right click on the image and select "View Image" from the menu. This will display the image in a new browser page and you can print it from there.

Even if you are on Windows and use IE, you can still use these techniques. No need to clutter your computer with unnecessary software. Knowing Windows tendency to develop "arthritis", avoiding unnecessary software can only be a good thing.
