Here's a link to a sign that's 36"x24" in Flash format. Can someone print it out (even if you have to 'fit to page' for letter size) to verify that it looks good? http://home.attbi.com/~advgoods/burncrapids.swf
One more note: From what I understand, the best way to print from Flash Player 6 is to right-click on the image and select Print from there. I guess you're not supposed to use the Print function from within your browser. .
