the good news...

...is that HP recycyles their print cartridges (for free/by mail!--no postage necessary if mailed in the US). I found that out when changing mine today.

The bad news is that a lot of my prints have these horrific lines running throughout them. I guess thats what I get for not spending 1 million dollars on a printer. I am going to send them some of my liney prints and see how they respond.
