Need a cheap compact home printer

Hello I need buying advice please

I only need to print documents occasionally but when I do I have to print quiet a bit it can be expensive when I go and print documents in a shop. I would rather not faff with inkjets printers so if a compact laser exists I would be interested in knowing your recommendations. I don’t care about colour printing I just want the cartridges or toner to be affordable.

Must requirements:

Not too expensive ideally £100 or less (I can be flexible to an extent)

Wireless printing from iPhone (very important)

As compact as possible (this is very important)

Let me know what compromises I should be making to fulfil my wish list
