The rpc.pcnfsd daemon provides users with the following printing services:
Connecting to a network printer and starting a print job
Browsing for network printers
Canceling or removing print jobs in network print queues
In order to support NFS print services, you must export the spool directory on the pcnfsd server. The spool directory has the default name of /var/spool on a SunOS 5.4 operating system or compatible versions and /usr/spool on a SunOS 4.0 operating system or compatible versions.
By exporting /var or /var/spool or /usr/spool, printing should work correctly. You cannot simply export the root directory ("/").
