I mean I only use my own printer once a year at most but plenty of other people still have to print things personally and professionally for various reasons. Many printed things can be replaced by technology but not everything. Fax was just a way to get information from one place to another - every single part of what it does is done better and easier with email and other tech

There's a few industries that cling to it for that (weak) reason but it's obsolete as soon as they let go

Oh damn well if 2 people are doing it in your industry, printers must be useless to everyone!

When I worked in the field I carried a laptop but still mostly worked off of paper. Paper-sized ectronics are pretty useless on ladders and plans are too hard to read on a phone. Paper can also fold and go in a pocket
