Bought a Brother P touch label maker.
I am not willing to use 8 AAA batteries (hate stuff going to the landfill) so I figure they take a plug pack, so no problems.
Right until I opened it up, and the plug is centre negative....
Come on, centre positive is the defect standard, its been years since I came across a centre negative device.
Worse, they use the same plug, so accidental polarity connection is extremely likely.
Most consumers don't even realise there is a difference (they barely understand different voltages)...if the plug fits then you use it, that is the way they have been trained with USB being ubiquitous .
How about sticking with standards Brother, there is NOTHING magical about your adaptor except you have the pin out reversed.
You can still hear the echo of the rude words I yelled including the claim that the engineers have dubious parentage...
