Printing directly on DVD's or CD?

This last round of DVD's I bought says that they are printable. How do I do it? I have a PIXMA iP300, I just re-read the entire manual and I couldn't find anything.

So.. Can I print directly on the DVD?

I'm guessing that my printer just can't do it or they would have documented it.

Thoughts?

are they 'lightscribe' disks? those are the ones on that HP commercial in which you can just flip the disk over and it prints on the top of the disk via laser.

that or you would need a different printer. what kind of disks are they?

I don't remember. I bought them off eBay. They were name brand and factory sealed 50 count. The little piece of paper on the top of the first disk said I could print them.

The disks are flat white with a somewhat corse surface, similar to the feel of paper.

Dam I wish I could remember.

or maybe there the ones that are compatable with the newest epson printer that will let you print onto the disk via printer , i think it's the only one that will let you print onto the disk , not 100% possitive but i think it's the only one , here is the line that prints to disks , Click Me
