This printer is one of the best for under £100, but for £50 plus delivery it is a steal. This refurb also includes 1 year manufacturer guarantee, the same as if bought new so the £15 saving is a bargain.
The printer has cheap refills and also 3rd party ones too, it's quick with auto duplex so perfect for students. Colour, but is an inkjet, hold that against it if you will, but try find a colour laser at this price point that is even slightly as good.
All in one, includes a scanner which is also a useful addition.
