Are there any certs or classes or anything like that for HP printers? ANything that would help get to the front of the line when ordering stuff like fusers and the like?

I spent 4 hours on the phone with them, I knew I needed a fuser, but they made me keep trying this and that and that and this(which all I had already done). Plus, I would just like to be able to do more troubleshooting and all.
