the printing backend revolves around a tdb database that stores the

SMB view of the print queue
|

|
The key for this database is a jobid - a internally generated number that
|
|
uniquely identifies a print job
|

|
|
reading the print queue involves two steps:
|
|
- possibly running lpq and updating the internal database from that
|
|
- reading entries from the database
|
|
|
|
jobids are assigned when a job starts spooling.
