HP DVD-R won't print label
DVDs have an extra layer of plastic over the light sensitive coating!
Try cleaning the LABEL side.
You may have to try another brand, but try taking the disks back to the store & see if they'll exchange them or help you try other brands!
I can only find Memorex or HP media & only had a problem with the 1st 2 spindles of Memorex CDs.
Cleaning allowed recovery of all but 1 which had a bad DATA side.
