Here is a simple solution to the problem.
I will add IE or Zoho/ThinkFree/other instructions, but the concept is the same.
On step 4: I have added a small footnote describing the situation in IE.
Step 1: Get Firefox
Firefox 2.0 is much better than older versions, because of the added spell checker!
Step 2: Write your paper!
Next, click "Preview" .
Step 3: Now click Print Preview...
You may feel like I repeated myself, however you need to have clicked BOTH the one on Google Docs, AND the one in FF.
Step 4: Down with the Header! Down with the Footer!
(Note for IE users: After clicking "Page Setup" and "Margins & Header/Footer", there will be two long textboxes labeled "Header" and "Footer", which appear to contain gibberish (Something like &s&b&d&t ), delete the contents of both of these to get rid of your header and footer.)
