Re: Computer Printer ports

Note that the minimum voltage level is + and - 5 volts but they can range as
high as -+15 volts.
Michael, this is kind of an old technology idea, but couldn't one just add a
simple Radio Shack relay ? A 5 + V. output can actuate a 5 + V. relay
which'll switch on 1 to 10 amps, for less than $ 6. ( not counting $ 15. for
a small power supply ) .
