I recently had to get printing working for a family member on an Apple tablet. I'm not an Apple jockey so it took me a while to sort out and I've being using computers since 1980 and consulting since 1995.

You tap an icon that looks like the outline of a rectangle with an arrow pointing up. Then you tap the name of the printer. Then you tap another rectangle with an up arrow and then tap the word "Print".

I may have got the precise steps wrong but it really is that abstruse to print something on a tablet. Never mind that mDNS/Bonjour has done its thing - the steps to actually indicate that you want to print is frankly weird.

What on earth is that box with an up arrow actually supposed to mean? Why does the interface switch from icons to text?

Android uses the 'share' icon to represent the same thing, which is maybe a little more legible, but still feels like shoving way too many actions under a confusing modal they shouldn't be in. Even worse when apps implement a custom share dialog.

It's supposed to be the "Share" menu, but that stopped meaning anything very fast because they just crammed everything into it for lack of other UX for system services.

Macs have the problem multiple times over, because now they have the normal menu bar and toolbar, and a Share menu that just gets arbitrary stuff dumped into by App Store apps, and the Services menu that shows up in some contexts but not others, and the Quick Actions menu that shows up in some contexts but not others, and some services can just add things directly to right click menus.
