PS2 barcode scanner doesn't work?

No, usually PS/2 scanners will simulate keypresses as if the barcode's value had been typed on the keyboard.

PS/2 barcode scanners are "keyboard wedge" scanners that plug in between a PS/2 keyboard and a computer's PS/2 port. When a barcode is scanned, they send the data to the computer as if it were keyboard input.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
