You might be able to wake it up with something like
   true > /dev/unlpt0

Or maybe use usbconfig to wake it up, in various ways.  Some might make 
it do the ink-wasting powerup, though.
   usbconfig -d ugen1.2 resume
   usbconfig -d ugen1.2 power_on
   usbconfig -d ugen1.2 reset

Don't know if that would work with the unlpt device directly.

HP says that printer is not supported with HPLIP, but not why.
