Hi Yorkie, OK, I've got some unexpected suggestions for you:
I'm not fond of inkjets for printing long documents, or for professional b&w documentation, in my opinion they're very very good, but not quite perfect enough.
I would therefore suggest you consider a laser printer to cover your b&w needs. The market has developed so much in the last few years that you can now buy truly excellent lasers which cost very little.
I would suggest that The Samsung 1520 might be good for that. Output will look stunning, it'll run for thousands upon thousands of pages without requiring cartridges and it will be mind blowingly fast. £100 inc VAT.
For colour photos, there a couple of good, cheap printers out there that I found on PCPro. Best value:
I expect the Canon IP 3000 will give you fantastic high quality photos. 80 quid inc to you.
If you wanted a more general all purpose colour inkjet, how about the HP Deskjet 7540 at just £65 inc.
Finally, you mention that scanning would perhaps be a useful extra. The HP psc2355 does scanning / photocopying and colour inkject output and costs £140 inc VAT.
Post any comments / queries and I'll help out as best I can. I know it is a bit of a head f*ck choosing these things, and I'm sorry my recommendation isn't simply an Epson X.
