How to Print Pictures in Web Pages
When preparing a web page for your printer, most browsers (Mozilla, Netscape, and Internet Explorer) shrink images on web pages so that everything will fit on a single printed page.
To get the largest possible reproduction of the image:
In Internet Explorer, right-click on the image, and select "Print Picture..."
In Mozilla and Netscape, right-click on the image, and select "View Image". When the image comes up by itself, print it. (E.g. select File > Print from the menu bar.)
