Thanks again, Bob! I wasn't aware that cheap Deskjets (this one's a
D1430) did this. It sounds like I'd be better off leaving the thing
on continuously until I shut down the system (which could be several
days later). Up to now I've been shutting it down (with its own
switch) every time I figured I was done using it for a while.
