No Xprint server(s) found. Check whether the XPSERVERLIST Environment variable contains any valid Xprint servers.

Need patches 112785, 113713. Need package GISWxprintglue.pkg. The patches are already on autoinst, but the pkg is not.

need to restart X server? One of the patches is to Xsun

/usr/sbin/pkgadd -d GISWxprintglue.pkg

/etc/init.d/xprint start

tell /usr/openwin/server/etc/XpConfig/C/print/Xprinters to look in lpstat or whatever for a list of available queues

This part was not in my source document:

XPSERVERLIST="`/etc/init.d/xprint get_xpserverlist`"
export XPSERVERLIST

mozilla doesn't appear to see new printers if you exit it and restart it. Trying to stop and start the xprint daemon without restarting mozilla... And that worked. So existing mozilla processes appear to see new queues on the system if you kill and restart xprint.

This one line diff makes Xprint work with plpd.
