Or if you can't switch jobs just yet, and you have time to kill at an Apple store, sit in on one of their daily tech sessions. I once went with my mom to the "Basics: iPad" session and couldn't believe how basic the topics were in the description [0]. But the attendees had even more fundamental issues than could be covered, such as file management, e.g. how to move a photo from the iPad to their home desktop hooked to the printer. I know that is actually not simple (it may even be covered in the Intermediate version of the class), but it's the kind of everyday feature that users expect to be simple.
I don't personally have a wireless printer (mine is networked though), but I've noticed that all of my non-techie relatives have bought a $50 HP in the last 2 years, and somehow they all have it hooked up to WiFi as the only connection. The printers must also implement AirPrint, because they show up on my Grandma's iPhone when she tells an email to print.
Printing photos directly from an iPhone was solved for everyone else and I barely even noticed it happening because I still print from my laptop.
As a developer, a backend app developer for that matter, I still don't know an easy way to do this. I would either sync it to my Google Drive, or fire up a local FTP server on my phone to do it.
Simple joke, don’t get flame baited. I’m sure there is something similar on Android but on iOS all you have to do is AirDrop to your computer. Takes 2 seconds.
