For occasional use, get a laser printer, not an inkjet. Laser printers don't clog if left unused for a while. They cost more to start with and the refills are quite expensive,but you don't have to refill them very often, so they don't cost any more overall and they are much less trouble.
I have an HP CP1515N and it works really well. I expect the HP CP1025 would suit your needs. It comes about £50 cheaper than the "free" Dell I linked to earlier, but the Dell comes with 3 sets of toner and the HP will only come with "starter" cartridges, so in the long run the Dell is probably cheaper.
The Dell also looks bulkier, so you might want to look at space before making a decision.
