This is the keyboard accelerator for Print. It has nothing to do with display scaling.
On a laptop / notebook there is sometimes a special keyswitch (one of the function keys) that is used to enable / disable the external display port. I'd first guess someone accidentally switch the port off. (I've been there myself several times. And had to reset other people's machines when they've somehow done this.)
You'll likely be waiting years (or forever) to have tray text changed. They've come from static dialog layouts and it is a huge job to convert them over to dynamic property panels.
They like the way they are laid out, and I can't see an overhaul being welcomed. All the help center article images would need updating as well.
Though, I could see a slow update over several years, a few panels per version.
