Here is a web site that claims if you follow these directions, the 720 will work for Win98SE
I'm sorry, but there is simply no driver available, anywhere, anytime for anything other than WinXP/2000. No amount of asking, pleading, or begging on this forum will produce one either.
The page you referred to above as the one you "didn't understand" is a bit technical. I was able to follow the instructions there and successfully print from my Win98 PC and laptop, and it has continued to work reliably for the last 6 months, but it is certainly NOT recommended for the "average user".
