I have had trouble in the past printing bricks coupons (coupons that you can only print twice).  It’s very frustrating to need 2 coupons, hit print and they don’t, and then when you figure out the problem and fix it, it says you have already reached your print limit and you didn’t even get one!  Before you get to this point:

I found this info and it works like a charm, so keep this handy when printing bricks coupons:
In the url in the address bar at the top of the page, somewhere near the middle you will see:
vi&o – This is for printing in Internet Explorer (IE) 
wg&o – This is for printing in for Firefox (FF);
xg&o – This is printing in Firefox (FF) on a Mac.
So, when you are ready to print and you click print and see the wrong letters for the browser you are using, just change the letters to the right ones and it should print!
