At home I've been using my printer less and less, though. I started printing to PDF archives after spending DAYS shredding old documents. I'm nowhere near paperless yet though.
Best way to go as long as you backup your computer files.
I not only print most stuff to PDF (unless I actually need a hard copy), I also scan any paperwork I might need and then shred it.
Years ago I was at the point where I needed another file cabinet, so instead I bought a double sided scanner and started scanning any paperwork I might need and then shredding it. I try to keep very little paper, and even emptied out half the file cabinet I already had. 10 years worth scans (I even scan at 300DPI for better quality), and I'm barely at 1GB.
