Of course that print preview would often make me reconsider printing a page. A lot of (badly designed) pages format really poorly for printing: Text ends up taking only very little space, squeezed from both sides by formatting that may look pretty on the screen but it absolutely useless on paper. Pictures may not scale properly and may be truncated. Etc. Without print preview, you cannot really tell how a page will print because the page may or may not support print-specific formatting.

Absolutely. In the past, I found myself copying only relevant parts of the page into Word before printing (on Windows) or editing HTML for the page (on Linux) when I wanted to get a good printout.

A workaround for absence of print preview is printing into PDF or PS before you go and spoil a lot of paper... but we really should not have to do such things in 2011.

I do not print nearly as often as I once did. But when I do, having a print preview - and ideally live preview where you can remove content that you do not want to print - would be a big help.

Funny that you ask :) Because just today I had to guess my password account. When I create a new password, I usually take the first word which comes into my mind and cripple it using upper and lower case, numbers and little cyrilic ... Then I write it down into an encrypted file.

But two day ago I had to change my password on a very ancient and dumb terminal and I couldn't save it (even vi didn't display correctly :( ). Of course I remembered the word but not the permutations I did with it... Now I have it again :) after trying almost all of 2**6 combinations that seemed possible to me :)
