I can see a couple other possibilities. If the computer is being put in
"soft off" every night, rather than switching off at the back, then you'd
still have +5VSB running. Some motherboards have a jumper, to set the
USB port to either run from the +5V supply or from +5VSB. Typically, the
purpose of +5VSB is to power USB devices that might be used to wake the
computer.

Maybe if the printer port was powered from +5VSB, while the computer was
off, the initialization sequence might work a bit better.

As an alternative to unseating the cable, there are USB switch boxes, where
you can leave the cables connected. Pressing the button on the USB switch
box, would create a similar event, to plugging in the cable. (Note that
some USB switch boxes have a really crappy button on top, and before too long,
the switch falls apart from usage. Check the customer reviews for any
evidence of that kind of thing, before buying.)
