If it's really few months of not printing anything, would it be more economical to use one of those print services instead? You lose the convenience, but you also gain a bit of shelf space for not storing the printer and all related printing supplies.

But what about privacy? Don’t you mind printing a copy of your passport or payslip or any sensitive doc via a print service (e.g., in a kiosk)

My time in not going to those places to pick up a job is worth more than the cost of a printer. I use those places for large prints - so far once in my life - but it takes valuable time.

The library's even cheaper. My library offers something like 400 b+w pages or 200 color pages per month for free.

I got an old dell mfp 3115 from a business that was moving for about a hundred bucks. I've never replaced the toner since I got it almost a decade ago and still have a compatible replacements. I've printed hundreds and hundreds of pages. I'll probably use it for the rest of my life or until I can't get the drivers to work. If you have the space something like that is an option.
