When was the last time you tried any of that on linux? Printers have been plug and play(which is impressive considering the hoops I had to jump through on windows) and with advent of proton, there's been no game I've played that's had any issues
An anecdote about printers: I was just trying out Linux Mint from a live USB when out of nowhere appeared a popup that a Brother printer was ready for use. Turned out my significant other had switched on the WiFi printer in the other room. I really had to laugh out loud about how unexpectedly easy that was.
Linux has been good for gaming for years now. I think I switched 4 or 5 years ago, and in all that time I've almost never had problems running games.
It has been a few years to be fair. However, back when I ran into the issue people said the same thing.
I might try it on one of my older laptops which are in the closet.
