Weird printing problems

[Vince]

I have a generic page that I use for printing content, and it contains
an iframe into which I put the url for the page to be printed. I
dynamically size the iframe so that it correctly displays the entire
contents of the printed page.

There are 2 problems with this:
1) The resulting printout chops off the bottom part of the page, even
though it displays the full page in the browser. Even in print preview
it still chops off the bottom. I wonder if dynamically sizing the
iframe throws off the browser's printing information.
2) Sometimes the browser doesn't resize the iframe correctly. The
iframe returns the wrong scrollHeight.

Here's the code I use to resize the iframe:
var h = document.frames("printframe").document.body.scroll Height;
document.all.printframe.style.height = h;

Here's the code to print:
document.all.printframe.focus();
print(); // FYI, I tried document.all.printframe.print();
// but that errors out (object doesn't support this...).

Any ideas?

Thanks,
Vince
