Do you mean LightScribe? I have one, actually this is my second one,
but I have not used the labeling under Linux. You need LightScribe
compatable disks in order to make the labels. The system works fine
under Windows. However, the disks are more expensive, you only get
black over whatever background color is on the disk, and it can take
20 minutes for the highest quality resolution on the label.

The unique feature is that you can go back and add to your label
later. There is a bar code around the hub of the disk that tells the
drive it is LightScribe and which way is up. So you can reburn the
label to darken it, or add additional content to the label, without
worry about regstration of the image.

This being said, I do not see LightScribe as the "next big thing" in
labeling. I also have an Epson R280 that prints direct to inkjet
printable CD/DVDs. While it does not support effortless updating of
previously printed disks, the printer does a very good job of
centering the image on the disk, prints in full color, prints a disk
in a minute or two, and the media is much cheaper.

Pluses for LightScribe, impervious to water and flawless registration
of labels for updating in a second run.

Pluses for inkjet, faster, full color, cheaper.

Both do away with the nasty sitck-on labels. Since I do not have a
real need to reprint the same label on a disk, the only real advantage
is the ability to resist water for the LightScribe labels. I do
occasionally use the LightScribe feature. Mainly for "car disks". My
wife and kids do a horrible job of taking care of disks in the car.
So I never put originals out there. (Life span is about 6 months.) As
much as they tend to drink sodas and handle disks at the same time,
the robustness of the LightScribe label helps ensure the label lasts
as long as the disk.

I suppose I could just write on them with a marking pen, but were's
the fun in that?
