I had the same problem and it took several tries to solve it.
First of all, you don't say what operating system you have. I have
Windows Vista. This is what I did.
I went to my control panel and opened the Programs folder. I
then found and deleted all Java programs and updates. Then I opened
my "Computer" folder and clicked on my "C" drive. I opened the
program files and deleted Java from there also. The next time I
wanted to print a coupon, it gave me a link to install Java. Once I
installed it from their link, I was able to print. I have not had
any problems since.
