I use a Bluetooth pocket size printer for shipping labels, but I unfortunately couldn't do without my color inkjet, even though I only use it a few times a year.

I'm really hoping they come out with some kind of A4 size color thermal printer for all these one off use cases.

It's just paper with chemicals on it, it probably shouldn't be more than 20 cents a page or so if it were scaled up to be the dominant type of home printing.

Bills need to be mailed to my health insurance company if I want to be reimbursed for anything — no online uploads whatsoever, and this is for one of the major national companies that everyone knows.

Every medical practice I know of still has a fax number, in 2022.

You're most likely in a different environment than the person you're replying to. Dynamics around landline numbers can also have surprising variance between countries.

You wouldn't be saying "everyone should be paperless" if everyone was paperless!

I resisted having a printer for many many many years (part because I didn't want to lose the space it'd take up, part because I don't want to deal with the toner cartels, and part just because I didn't think I needed one and it was fine to make a trip to FedEx Office when I did), but finally caved in a couple years ago. I'm surprised at how often I use it and find it useful, and how little a hassle it's turned out to be. (It is also a scanner, which I've found just as useful as the printing aspect.)

"Everyone should be paperless" -- either you live in a country with a unusually advanced, tech-minded government, or you're just completely out of touch with a normal person's needs in a place like the US.

I live in the US, never needed to print shipping labels, never needed to print craft things (my hobby is electronics), and I have dedicated document scanners to convert the few things that still come on paper into electronic documents

Shipping labels, tickets etc. Printers suck, but I can rely on paper being suitable for its purpose. Can't say that about most alternatives (mostly phone apps).

Should be, maybe, but isn't.

To give one trivial example: if you're selling vinyl records on Discogs, you need to print the mailing address to put it on the package.

Where I live you'd upload that to the post office and they give you a QR code you can use when you hand the package over.

(OK you probably wouldn't, but you can)
