simply typed in epson 950 and got a 3 page write up which includes this. CD printing
To print directly onto a CD, you need to use a CD that has a printable surface. These are available now and you can also pre-attach a CD surface sticker from a kit. You can’t simply print onto the bare plastic of a standard CD as the ink is water based and will easily smudge, even after drying.
A CD holder is provided and you can also use an adapter for the standard smaller CD size commonly available. The holder and CD are mounted from the front of the printer, after removing the paper cutter unit, if present.
Epson provides some easy to use and flexible software for designing your CD art work. This allows variable size borders, fonts and the addition of graphics. Text can be manipulated to follow the rotation of the CD.
