Hello,

I would like to know what is the maximum width I can make my webpage
if I want a user to be able to print any page (using the print button
on the browser) and have it print exactly what is displayed on the
screen?

The current site gets the right margin truncated at about 660 pixels.
I was under the impression anything under 750 was printable. How can I
ensure what I see on the screen is what will print on the page?

Thanks.

I think that perhaps 750 pixels may be printable with zero margins
(most page printers are unable to print with true zero margins). 
However, a total width of 680 pixels appears to accomodate typical
margins.

Personally, I like to use a width of 580 pixels to have a margin of
error.

The following link offers a page that you can print to see how various
widths appear on your printer:

Since it sounds like precision printing is important to you, it is
worth noting that Mac and Windows computers tend to handle fonts
differently.  This can cause differences in the printed page from
platform to platform.  You may be interested in the following articles
dealing with this topic.  Both explain how to use Cascading Style
Sheets (CSS) to overcome these platform differences:
