Is it still necessary to own a printer?

The experience of living in a digitalized world attempts to be friendly with the environment by avoiding waste of materials that will be ending in the landfill. Let us focus on printers.

Now, we just download and edit the document in our computers and resend it. This leaves us with the question if we still need printers or they will slowly die out?
