Yamaha is about to release a new CD burner that is not only ultra−fast but it can also burn images on the FRONT of the CD like this
That's pretty cool!
I'm not sure which I like better. Printing to a label which can be colorful or just printing on the CD which is probably easier. All the top end Epson Ink Jet printers in Japan have a CD tray built in to them for printing directly on the CD.
Of course if you want to use the Yamaha burner you have to by CDs that have a burnable front surface.
