When at least one local or remote printer has been configured on the system, the `Set Default Printer' option is available on the Printer Administration main page.
Netra printer administration sets a system-wide default printer.
However, there are a number of ways for individual users to override this value: by using a ~/.printers file; by setting the LPDEST environment variable; or by setting the PRINTERS environment variable. Once any of these are set, an lpstat -d reveals their value for the default printer, not the one quoted in /etc/printers.conf.
If the system contains a /etc/printers.conf file, and there is also a NIS printers.conf file available, the NIS default value may be the one used.
If the user unsets the LPDEST, PRINTERS variables and removes the ~/.printers file, then the Netra setting of default printer is the one quoted by lpstat -d.
