I too have been trying to go paperless. I scan all my papers into Evernote using a ScanSnap scanner which means they go straight to Evernote. I send a lot of e-mails to Evernote automatically, and print receipts etc. straight into Evernote as a PDF. I have a Notebook called _Inbox into which all notes are sent first. From there its a matter of a few moments once or twice a day to assign them to their proper place, and to tag as needed. Sadly, as I run a business I have to keep some of the papers I scan so I still have a working filing cabinet. Unlike Nico I have kept the printer as there are times when I need to print off papers. Usually when I create a handout for a presentation. I've found that for me the best way to keep the paper down is to scan and assign in Evernote regularly throughout the day.
