PRINTERS
Still printing articles to “read later”? Get over it. Almost any
cellphone has a good enough screen to read text. If you have an iPhone,
you can even use the “Instapaper” application to automate the process — hit the Read Later bookmarklet and enjoy the article later, away from your desk. The forests will thank you for it.

SCANNERS

If you regularly scan text documents and use OCR (optical character
recognition) to make them into something other than dead trees, you can
forget that, too. The average cameraphone can take a clear enough
picture to read the text, and from there you can either email it to a
service like ScanR (which converts your pictures to editable PDFs) or just drop it into EverNote, a cross platform application which does the same. Your filing cabinet has never been so empty.

FAXES
why not just email the PDF?
