I have some white label discs which were sold as "printable", does this mean I can print sticky labels for them or do I need a special printer? Also is not recommended to stick labels to ordinary -R, for example Sony or Maxells, if I do, what problems may happen? I have read of the possibility it may fall off in the player due to heat. The reason for asking is that I have just bought a label set and I don't want to damage discs/player etc. Thanks.
