It's not HP. In fact, it only happens when I'm on the mudcat, so now I'm suspecting some sort of tracking done by mudcat.

By the way, I bought a $98 hp officejet 4215 all-in-one which does printing, scanning, faxing, copying, and I have to admit I love it, now that I got rid of all the HP automatic updates. Has a very small footprint and works well, replacing several pieces on my desktop, and good enough quality for what I need.
