The Printer? Holy spitwads. I have an HP printer (and run poser on an HP machine), and I do get the massively annoying "ding"s all during the render process. It didn't start doing it for me until I added on the ProPack, so I just assumed the "ding"s were another in the long list of PPP glitches. Before I uninstall stuff, are you certain these are printer related?
