I've heard of things like that. For that reason, I've always made
sure that whatever inkjet I have has its power off (by switch or by
software) before killing the "master" power (power strip or UPS).
My scanner is separate, and it does have a low power mode that it
goes into after a while, but I only switch it on when I'll be
scanning, and off when I'm done with it.

Ha! I beat you! :-) I got this dinosaur HP Color LaserJet 5M for
free. Of course the thing dates from 1997, is the size of a large
window air conditioner, weighs 102 lbs. (46 kg) empty, takes several
minutes to warm up, is incredibly slow in color, and is a power hog,
so I can see why the guy wanted to give it away before he moved.
OTOH the cost of consumables and parts thru eBay is almost nothing.
Electricity is another matter -- even its "power saver" mode draws
30W.

Well, at least both of us now have working printers.

Y'know, that's a really good point. I just never thought about it,
and plugged all the computer pieces into the power strip (and now
the UPS). At least I plugged the printers into the non-backed-up
side of the UPS. :-) Thanks VERY much for the suggestion!

That IS what a large number of "only print occasionally" users do.

Depends on how often you need to print.

Thanks very much! That puts things in perspective nicely. Now that
my dinosaur laser printer is working again (way cheaper per page), I
probably won't be using the inkjet very much. Hmm...

Generally Deskjet printers have an internal clock that tracks the time since
the last print job and does more or less servicing of the nozzles depending
on how long it has been. If you remove the power to the printer the clock
loses track of time and when the printer is turned on again it assumes the
worst case. This will use more ink for servicing than is necessary.
Besides higher printing costs this can also shorten the life of the printer.

I would recommend keeping the printer plugged into an active outlet.
