When printing documents that use CSS to position DIVs absolutely, the size of 
the page does not take into account the top and bottom margins when computing 
the size of the "page". I defined a DIV called footer to have the following 
properties:

#footer {
    position: absolute;
    width: 100%;
    bottom: 0in;
}

This is correctly positioned in the browser, and if I set the top an bottom 
print margins to 0, it is also positioned correctly. However, if I set a top 
margin of 1 inch, the whole layout shifts down one inch. The effective height 
used to calculate the absolute position stays the same, so my footer div gets 
pushed partly off the bottom of the page. 

This isn't the correct behavior is it?

Reproducible: Always
Steps to Reproduce:
1.Load my attached page
2.File -> Page Setup. Set top margin to 1
3.Print or print preview.

Actual Results:  
Footer div gets pushed off the bottom of the page.

Expected Results:  
Expected it to align the bottom of my footer div with the top of the bottom 
print margin.

I also tried using media specific css sheets (@media print) but this did not 
change anything. Changing the bottom print margin also had no effect on the 
positioning of the footer div. Aligning to the left, right, and top of 
the "page" all appear to work fine (they align relative to the margins), it is 
just aligning to the bottom of the "page" that has problems.

I just noticed that this works as expected when using fixed positioning instead 
of absolute positioning, so that is a partial work around except that fixed 
positioning repeats the div on every page, while absolute positioning only 
applies to ... actually I'm not quite sure what it should apply to, now that I 
think about it.
