A Windows NT (print) server keeps track of all information needed to serve its duty toward its clients by storing entries in the Windows registry. Client queries are answered by reading from the registry, Administrator or user configuration settings that are saved by writing into the registry. Samba and UNIX obviously do not have such a Registry. Samba instead keeps track of all client-related information in a series of *.tdb files. (TDB stands for trivial data base). These are often located in /var/lib/samba/ or /var/lock/samba/. The printing-related files are ntprinters.tdb, printing.tdb,ntforms.tdb, and ntdrivers.tdb.
