Trusted Extensions uses labels to control printer access. Labels are used to control access to printers and to information about queued print jobs. The software also labels printouts. Body pages are labeled, and mandatory banner and trailer pages are labeled. Banner and trailer pages can also include handling instructions.
The system administrator handles basic printer administration. The security administrator role manages printer security, which includes labels and how the labeled output is handled. The administrators follow basic Oracle Solaris printer administration procedures. Configuration is required to apply labels, limit the label range of print jobs, configure labeled zones to print, and relax print restrictions.
Trusted Extensions supports both multilevel and single-level printing. By default, a print server that is configured in the global zone of a Trusted Extensions system can print the full range of labels, that is, the print server is multilevel. Any labeled zone or system that can reach that print server can print to the connected printer. A labeled zone can support single-level printing. The zone can connect to the printer by way of the global zone, or the zone can be configured as a print server. Any zone at that label that can reach the labeled zone, and hence its print server, can print to the connected printer. Single-level printing is also possible by using the print server on an unlabeled system that has been assigned an arbitrary label. These print jobs print without a label.
