Are you talking about printing onto paper labels, or onto printable discs? Just wondering, because it is a horrible idea to print onto the paper ones and then stick them to a DVD, the disc might (if you're lucky) work for a little while then it will most likelt just stop working one day because of that paper label. As far as a program, I use the Epson software that came with my R220 printer. I have tried others but none work as well or are as easy to use as that one.
I used paper labels for some time before discovering the Epson printer that prints directly to the DVD printables. Have not used a single paper label since.
