I did buy a (Brother DCP-J4120DW) colour inkjet printer all-in-one device. And (surprisingly to me) it actually doesn't suck. The Linux drivers work. Sure, the ink is pricey, but it has generally been trouble-free. I left it for a couple of years without printing anything and it clogged up, but when the pandemic hit and I started having to print at home again, it cleared up with a couple of head-cleaning operations. I'm not printing much - maybe a double-sided sheet a week.

So yeah, the advice to never buy an inkjet - it's true but not disastrously true all the time.
