Re: Turn off laser printer with power strip?

Power strip is a surge protector without those internal $0.10 parts.
Both power strip and power strip surge protector connect that laser
printer directly to AC mains. Remove those $0.10 parts from a power
strip protector and install those parts inside a plug. When that plug
is plugged into a power strip, then the power strip is electrically
same as a power strip surge protector. Those parts - inside the power
strip or inside an attached plug - make no difference to how a laser
printer connects to AC mains.

I will love to see this poster prove that one. Yes, that is an open
challenge. What is a power strip surge protector? Assuming it has an
essential 15 amp circuit breaker, then that surge protector is
electrically equivalent to a power strip ... as long as voltage never
exceeds its let-through voltage rating ... 330 volts. That's right.
That $25 surge protector does nothing as long as AC voltage does not
exceed the let-through voltage. That $23 protector is electrically
same as the $3 power strip when 120 volt AC does not exceed those 300
volts. This idea that high current devices 'interfere' is classic junk
science reasoning - complete with no reasons 'why' and no numbers.

Turn off laser printer power either using its power switch, using a
power strip, or using a wall switch. It's all the same and not
destructive to the laser printer.
