As for the printer. I tried the 660 model, the 952 model and the 1120 model of HP's and each one the minute I installed them, I would start having problems with poser. Most times I could not render to a new window or it would just lock up on me when I would start to render. I would have to cntrl alt delete to get out of poser or on the new window renders it would give me a blue screen. Sometimes I would have to just hit the power off button also. I know for a fact it was the printer in my case. I now have a canon printer installed and have no problems. I do not have pro pack so I cant say on that.
