Switching adaptars are standard power supply that  are used to power just about anything.  The switching adapter part regulates the power.  As to what specifically yours is to, unless it says it on the case it is hard to tell.  It will work for about anything as long as you make sure the input matches exactly what you are going to plug it into.  And of course if it fits.  

Make sure before you try plugging it in that the input and output and polarity on the adapter is the same as on the bottom of the device you are trying to plug it into.  You can ruin the device if it is not the same.

I have a box of unknown adapters.
I'm trying to throw away, the ones that specifically go, to a specific, device.
A device that I do not own.

If this adapter could go to multiple devices, I'll just keep it.

Yes it can, provided that you check for matching volts and watts etc.  the device, printer or whatever, will have a little sticker usually near the power plug indicating that information.  if that matches and the part that fits into the device matches, you are good.  

Radio shack makes a living selling these adaptars, calling them universal, to replace ones people have lost.

yes.  the switching part looked a little small for a laptop, but who knows.  as far as printer, scanner, fax machine, switch, etc.  it could work.
