> flacky without) and USB.

> The easiest way to see if will get any problems is to connect it and open a

> Some applications require a software wedge to handle the serial input.

> The USB and PS2 based units we used at work just emulate a keyboard.
> Usefully you can add prefix and suffixs to the scan i.e. the scanner can a
> "Enter" key to the end of each scan.
> We use Symbol (by Motorola) scanners at work and find the scanner very
> robust. They also use a common cable, i.e. for a wired scanner, you purchase
> the scanner + the cable type you require, so you could be one scanner and
> all three type of cable and switch between them by simply swapping cables.
