I'm not familiar with your model of printer, but some printers can produce an approximation of black by mixing the tricolour inks, so you could perhaps manage without the black cartridge. But it would be a very expensive way of using your printer.
I buy Epson compatible cartridges for my R300 at this outlet (buy several packs to make the most of delivery charge); the printer uses six separate cartridges and the price is just over £5 per pack of six. Genuine Epsons would cost around £60 upwards for the six...:-(
I am not more familiar with these HP printers but i can tell you to how to refill your cartridges. For refilling process,just take a refilling kit which comes with syringe and ink.And one important thing is that it comes with whole instruction of refiling process.So it will become easy for you to refill your cartridge. And if you want to save your money,you can prefer re manufactured ink cartridges.They are same as OEM and available at less price. ---------------------------- click here
