At the time it was a matter of expediency. We were in Maine sans printer and Gary pointed out a $30 one at WalMart. IIRC I was trying to figure out how many 6' printer cables I needed to hook together to run from the front of the coach to the bedroom and how I could do that without Chris getting on my case. Gary saw my predicament, felt sorry for me and offered to part with his new adapter that wouldn't do what he wanted.
BTW that little printer has been a workhorse, as has the adapter. If it's not broke, don't fix it.
