2. Using 4L-cli
There is one subcommand for every use case commonly encountered when using LightScribe.
2.1 Drive enumeration and identification
The
4L-cli
enumerate subcommand allows to list all the available LightScribe-enabled drives on the system. The drive path allows to identify each
drive uniquely (even if two drives of the same model are present, they will have a different drive path). Other informations include
:
• The current state of the drive (Usable: 0 or 1)
• The name, model and manufacturer of the drive
• The printing capabilities of the drive
• The radius range reachable by the drive (in microns)
