That PSU has no prolems with the current peaks for the printer stepper
motors, or indeed, firing the thermal inkjet  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
 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.
