I have used Chrome for years and I have never seen DPCs spike enough for me to go looking for them. In fact I like chrome as it is multi-processor aware and doesn't have the memory leaks that Firefox has (you have to go back to version 3 of Firefox to get rid of the memory leaks).
I don't deny that Cloud Print may be contributing, but there is something else going on under the covers. Neal, that is amazing that you got it down to that level. You and I know how much work that takes. If I get a chance, I will see if I can replicate it. We have at least 4 printers in our house, all shared, and I just haven't seen this.
