I only print around once/month (or less), and I've given up on having my own printer.

I get stuff printed at the local library now. Yeah, the per-page costs are relatively high, but I'm not amortising the cost of a printer, I don't have to worry about any kind of ink/toner/printhead/other mechanical issues, and any "profit" that's being made goes towards my local library - which I'm totally fine with.
