From the man pages:
     Access control is provided in two ways.  First, all print
     requests must come from one of the machines listed in the
     file /etc/hosts.equiv.  Second, if the ``rs'' capability,
     which restricts remote use of a printer, is specified in the
     printcap entry for the printer requested, lpr requests will
     only be honored for users with accounts on the machine with
     that printer.

Thus, Hans, you only need to enter your Sun node names
in /etc/hosts.equiv to make them acceptable.  Well, almost
acceptable, but they'll be able to print, at least.  That is,
as long as you don't invoke the ``rs'' flag.  It will require,
however, proper functioning on the Ethernet.
