hi ,
it may be worth checking for version 5.2 of HA but the only thing you can shared is the spool files , creating print queues have to be done on both servers
basically you create an application server in hacmp e.g called printers and add this entry in your resource group where it calls application servers and have start and stop scripts which have in them
start_script
stopsrc -g spooler
sleep 5
startsrc -g spooler
stop_script
stopsrc -g spooler
You also have to create
/var/spool/lpd/qdir
/var/spool/qdaemon
on the shared disk area
