Need to show proof of residency? Bring a copy of a utility bill (which is now paperless so I have to print it.) Make a change on my car or health insurance? Sure, I can wait a week for them to mail me a copy, or I can print a copy right now (because a family member lost theirs or needs to submit a copy for employment purposes.) "For faster service, please fill the documents out and bring them with to your appointment." Not a requirement, but saves everyone time.
I used my printer weekly when my kids were in school, but now that they're in their 20s I still find myself needing to print something every month or two. Sure, the 10 minute drive to the library is an option assuming I have the time to make the trip during their hours, and hoping it's not the opposite direction of where I'm headed. The last printer I bought was a basic Brother color printer that I spent $30 for on sale. It does a solidly adequate job 6 years later.
YMMV with all these examples. There have been multiple times where I have emailed a utility bill or signed lease. My insurance has an online portal to change my car or house insurance (sorry I don't have health insurance).
I get it though. This basically comes down to companies that suck and still use fax machines.
It's easier to read for understanding off of paper. Easier to mark up text and make notes. Easier to learn off of. The use and flexibility for learners and knowledge workers is still unchallenged.
