Sneaky Rip off Merchants!

I had to replace my printer, it was an epson because A) it broke and B) the ink shot up in price.

So i hunted around and found a brother printer, all in one 50 quid.,bargain! Right, found the ink for 1.34 per pot,(normally 20quid for four), it uses four different colours. black/m/y/c!

For my printing needs, I only need black. I ran out last week, bought some. For some reason i've haven't used the m/c/y colours-but they've ran out! +the printer won't let me print because they've ran out!
I guessed i wasn't the first to find this out, so i don'e a search and this is what came back!


Title:
Can I print using only the black ink cartridge when the Color cartridges have run out?
Description:

No, your Brother machine is designed to stop ALL printing operations when any of the ink cartridges are empty. This is to ensure the life of the print head and maintain premium print quality. If the unit were to continue printing, print jobs and cleaning cycles would suck air from the empty cartridge and damage the print head. The only way to continue printing is to replace the empty ink cartridge(s).

TWOTS!

Anyone recommend a printer? I can't be arsed replacing four inks, three of which dissappear and I don't use!
