Let's take a look at Lightscribe vs. Colour Inkjet printing shall we?
Lightscribe:
Only ~$20 more then regular DVD Burners, however would require a brand new DVD burner if you already have one you like
Media is in short supply currently, and carries a large premium over regular media
Time to print a full disc is ~20min, will be shortened to ~10-15min with later revisions of drive and media
print is monochrome (old-school gameboy style) only
Waterproof printing style (I THINK!)
No Ink costs!
--------------------------------------------------------
Inkjet (with Epson style printer):
Additional $100-$120 initial cost, however doesn't require replacement of your DVD burner
Media is widely available in many different "flavours" usually carrying a small premium over regular branded or silver surface media
Time to print a full disc is usually ~5min
Full colour printing
Printing is water soluable
Ink cartridges are an additional charge

Did I miss anything?
Based on my above observations, I prefer inkjet, but people need to make their own decisions.

Punch Cards -> Paper Tape -> Tape Drive -> 8" Floppy Diskette -> 5 1/4" Floppy Diskette -> 3 1/2" "Flippy" Diskette -> CD-R -> DVD±R -> BD-R
