Servant of Cats: Thanks for your reply. My experience with AirPrint is mixed so far. It doesn't seem to support duplex nor disc printing. Perhaps I'm missing something?
I have an old Canon all-in-one printer for which there are no Sequoia drivers hooked up via USB. Pretty sure that AirPrint is the only reason that I'm able to print to it from this Mac.
I do two-sided (duplex) printing fairly often. Haven't printed the labels of any printable yet - but the option seems to be there, if one clicks on the "(i)" next to "Quality & Media", and then selects an appropriate "Media type".

That's why I've relied on manufacturers drivers. My current machine is a Canon Pixma iP7250, but it keeps mucking me about. Maybe it doesn't do well with AirPrint which seems to take over. I suspect my wife's printing (wirelessly) from her iPad which could default to AirPrint, but can't prove that.
Canon Support – Canon PIXMA iP7250 – Drivers
That printer may have drivers for recent versions of macOS now. But if the day comes when Canon stops updating the printer driver for new versions of macOS - the way they already have stopped updating drivers for older Canon printers - it may be very helpful that the option to switch to AirPrint is there.
