Printer Ink Cartridge?

Need to get a black ink cartridge for my printer but not sure what size. It's a HP Photosmart 2575 All-In-One





The colour cartridge is 343. Do I get the same for the black cartridge or is it different?





Please help me if you can!





Thanks,Printer Ink Cartridge?
The HP 2575 ink cartridges are different depending on what part of the world you live





Read this, I found this by googling - HP Photosmart 2575 ink - and then going though the the first result being the HP ink site.

It's HP Black 336 or 337. Choose these on the capacity that they have . Most probably 336 will be cheaper and will contain lesser amt of ink than 337
Try this link - for Black Ink there is a high volume and a standard volume. There is no mention of a 343 cartridge though so perhaps check the colour cartridges against any other numbers on your cartridges.
