I buy plain white printable discs and have a printer which can, in theory, print on them.
It did for ages but now doesn't. For some reason many printable discs you can buy work with lasers but not jets (which mine is). So make sure you can get the discs you need for the printer you get. Mine is a Canon Pixma 4200. Good for general stuff but would not recommend them based on the running cost of new ink. (I just buy 3rd party black ink now and only do B/W printing)
