Hi Russel,
for the printer setup: start PCC -> System -> Manage system services and make sure cups is running, or started at boot. Then go ahead and add your printer 
-p.
This is getting more confusing. I have ticked the "On boot" box for Cups, rebooted and still clicking on "Set up the printer(s)..." gives no response.
I have two printers connected. HP Deskjet f4280 and HP laserjet 1018. I set them both up using hp-setup and then used Cups to set the Laserjet as default. The Deskjet works on bootup but I have to switch the laserjet off then on again for it to work. I will try uninstalling them with Cups, reboot, and see what happens.....
O.K., done that - stranger still - the network connection didn't come up. I had to go to "Configure Network" and set it up again.
"Set up printer(s)" still does not respond - what command should it issue? I thought it was PrinterDrake but that doesn't seem to exist on my system. I have set them up again this time using Cups alone. Will try a reboot....
Both printers now OK and network comes up OK. Also note that bootup is faster. So no problems here except that PCC "Set up printer(s)" still does nothing
