Choosing a printer

Hello,

I have decided to get myself a laser printer.

My intentions are to have a working printer occasionally. So sometimes I will print a lot, but then it can be left unused for a couple of years and I want it to be usable in the instant I want it without having to go and get new whatever.

My question is are there any considerations besides the printer being listed at https://openprinting.github.io/printers that I should make?

I will not hunt down the most open (as in copyleft/libre soft- & hardware) printer but would not mind it being open.

More importantly is the expectation that I could find new toners (I think that's the word for "ink" in laser printers) in 5 years.

I don't really want color, but if it isn't that big of a difference I might as well.

(I could change my mind to get a different kind of printer, but you'd have to be really convincing.)
