Netto have a lexmark all-in-one for £29.99 from monday 9th july in-store.
I believe they had this deal on a similar printer in March this year, but this is a slightly better spec (i.e. 17ppm as opposed to 15ppm before):
Details from the catalogue:
Prints, copies and scans
Fast printing of colour and text documents: up to 17ppm
Direct photo printing with PictBridge compatible digital cameras
Easy bordless 10"x15" copy button
Doesn't state which model, nor further spec given. Also bear in mind Lexmark cartridges can be more expensive than other printer makes (but I use CartridgeMonkey.co.uk for very cheap and good quality refills)
