That PSU has no prolems with the current peaks for the printer stepper 
motors, or indeed, firing the thermal inkjet [1] cartridge. Or the head 
load solennoid and head stepper motor in that disk drive. I can't believe 
the startup spike of the spindle motor is a problem

[1] I am told that Thinkjet was a contraction of THermal INKJET.

The machine is very well sheilded inside. Maybe that's the reason, but it 
seems a litle unlikely.

That,a alas (after all, it's an HP) is the most likely reason.
