Protectors that don't have a dedicated 'less than 10 foot'
connection to earth may even contributed to damage of a printer. Surge
earthed, destructively, through that printer. What is damaged? Well
what was a surge path through that printer? Your printer suffered
damage when on a plug-in protector? We have seen that often. Makes
little difference whether the appliance is powered on or off.
Destructive surges seek earth ground. Either surges are earthed
before entering the building, or they may find earth ground,
destructively, through household appliances.
What must be fixed in your printer? Nobody can answer without
opening it and making a analysis at compoent level - to find what that
path to earth was. You could try to self test - where certain buttons
are held when power is turned on. If it works then the adjacent
protector shunted a surge, destructively through printer's data port -
via the computer. It is normal for surge to also travel through
computer data port without damage. But even that solution requires
the shop.
Sometimes you can get lucky. A surge constructed an electrical
connection that only blew an internal fuse. But again, it sounds like
you don't have sufficient technical knowledge to replace it. And
contrary to what was posted, a VOM while holding down the power button
canont detect that fuse as good or bad.
Learn a lesson here. Blackouts don't cause electronics damage. A
surge was permitted inside the building. Surge therefore found many
paths to earth - as least one destructively through your printer;
maybe because it was on a plug-in protector. Those plug-in protectors
have a history of compromising protection already inside all
appliances (ie printer). Only remaining question is the path of that
surge - to identify what hardware was harmed. But again, that
requires sophisticated tools. In fact, service techs typically cannot
make such analysis. They, instead, just swap electronics until
something works. Only the shop can save it now.
Notice what was damaged. The item that was on a plug-in protector.
It is a common problem with protectors that don't even claim to
protect from the typically destructive surges.

I have an HP Business Inkjet 1200. I bought it about a year ago, but it
was a refurb. It's always worked well.
We had a thunderstorm last night, and the power went out. I have the
printer plugged into a surge suppressor, but I wasn't able to shut down
the computer before the power outage. Nothing else seems to be
affected.
I can't get the printer to power on. When I press the power button,
nothing happens. The power cord has a small LED on the end that plugs
into the printer, and it lights up when the printer is plugged in, so
the power cable seems to be working. I tried unplugging it, plugging it
back in, leaving it unplugged for 10-15 minutes, etc.
I'm afraid the printer might have been damaged in some way by the power
outage, but I'm hoping there's some other explanation or way to fix it.
