I have half a memory that Kodak are about the best in terms of pages-per-pound of ink usage. I don’t know where I’ve got that ‘fact’ from though, I may have made it up.

They were making that their unique selling point – that their cartridges lasted longer than everyone else’s.

mine wouldn’t let me print black even though I had a full black cartridge in it on account that the Cyan one was empty! I had to buy a full set of inks to print in effing black!

My Epson did that a while back, and none of the regular dealers, like Curry’s/PCWorld, keep the appropriate inks any more. On line, a set of six ink cartridges are nearly sixty quid, about ten quid each. So I bought a complete set of six for around eleven quid from an online seller. They work perfectly.
