I have to say that I definitely agree with the printer issues. The drivers just aren't up to scratch. I ended up having to switch to a different printer to get it to work for me.
I don't agree with the bit about time formats, though. I really like the customizability of them and took advantage of it to make a format that looks nice (to me, at least).
About the time format thing: I'm not against customization. Being able to make the time format look however you want is awesome. However, in my case, all I wanted to do was change the default 24-hour time format to a 12-hour one. That was it. And that took Googling "how to change time format in Linux Mint" and copying and pasting %a %b %e, %l : %M %p to do. Was that hard? No. But it wasn't intuitive (or at least it wasn't to me), and in my opinion shouldn't have been necessary for something like that.
Hmm, that's odd. I guess they changed it at some point. On mine it includes a button that says "Show information on date format syntax" which takes you here. The page is actually quite nice, including presets, references, and even a "build your own" date format.
When I made my own, I just pulled up the reference and started playing around. It really wasn't that difficult (or unintuitive).
Yeah, I think that might have came later or in an update, because when I was trying to change it at the time I don't remember the interface providing or linking to any kind of formatting reference. The site you linked would've been mucho helpful.
