I'm puzzled and annoyed. HP network printing has always "just worked" (with a static IP, anyway).

Turns out it was a bad interaction between the McAfee firewall and a couple windows components. The firewall was blocking all traffic from dashost.exe and spoolsv.exe, and the firewall log suggests both are part of the printing subsystem (well, they were blocked just as I test printed), and both were recently updated by MS.

I imagine McAfee will fix it sometime...
