Just FYI, if you have a Core i5 or i7 CPU, the 102% CPU reading could easily be explained by Turbo Boost, the dynamic overclocking of individual cores to meet short term processing needs. Activity Monitor things you have say a 2.5GHz CPU, and so when Turbo Boost kicks in to bump you to say 2.7GHz, the only possible interpretation for CPU monitoring software (unless it's specifically written to be aware of Turbo Boost) is to say it's over 100%. Which, technically, it is.
As for the rest... Ever since the joys that were the Carly Fiorina years at HP (and may any and all deities that ever were, are, or will be, help us if she wins that election)... HP drivers appear to be written by people I describe as dyslexic masochists with a bad attitude. The reality is more likely that about 5 different departments at HP send competing specs to some Indian or Chinese software outsourcing company, paying maybe 75% of what it'd cost to have the job done well, and what you get is the predictable steaming pile of excrement. If CUPS, which is included with OS X, supports your printer, you should move to that driver ASAP. Those are developed by people who will actually be using the thing, not some anonymous developer in some developing nation who is just looking to get a paycheck, and could care less about the overall quality of the finished product.

You can see the same thing on any Dual Core iMac. Basically, each core can go to 100% usage, so if for instance a multithreaded process is using 90% of one core & 12% of the other, Activity Monitor would show it using 102% in the "% CPU" column.
