I've had a very reliable HP1120c A3 printer for the past 6 years. Reasonable amounts of ink in each of the B&W and Colour cartridges. HOWEVER, the latest HPs have miniscule ink cartridges- about 9ml in each of 5 or 6 cartridges. My local refill shop says that they last hardly any time between refills.
You're cheaper to replace your Lexmark printer than to buy refills!
My local refill shop also suggested the Canon Pixmas are the bet buys at the present time.
