Taken from the user manual of a now defunct drive I used to have,and I quote :
"Labelling time depends heavily on content, hardware, media and print mode used. Typically for title only content, a labeling time of 2-5 minutes can be expected. For full disc graphics in Best quality mode, labelling times of 20-35 minutes can be expected."
From what I can remember the times given above are a little ambiguous to say the least.Coupled with the cost of media it would probably be a lot easier and cheaper to get a printer with a CD printing facility.I did!!
