Just upgraded to Win7 from XP.
I've got an HP Deskjet D4360. I downloaded the latest print drivers from HP and installed all that.
However, printing anything without margins set (EG Emails from Outlook, or Web pages) the text on all four sides of the document will be cut off. See below - the first couple of letters are missing from the left of all paragraphs. And the "1" is missing form the "Page 1 of 1" on the right.
So it looks like Windows just need to scale down the whole page a bit....
