Use a pen! Economical, cheap and lasts ages!
lol
Probably Epson or Hewlett Packard - either I would say are better than Lexmark (thrown 2 of them in the bin so far!) Then order compatible ink cartridges off the internet, which are cheaper and will be full. Buying a manufacturers own cartridges you always find are never full, this is why they never last very long.
[HIDE]OR... Buy a colour laser printer - really depends on often you would use it, but they are economical. Black and white lasers can be purchased for as low as £50 these days, and capable of printing 5,000 A4 pages per one toner cartiridge.[/HIDE]
