The question is the other way around. What do you try to do?

I use any, as keyboard. But I just scan own codes with special heading, so I scan everywhere and any form catches the input and redirect to a handler.

For a scan into a special field w/o setting focus to the field one can try to do a timing trick. The scanner is usually faster then kbd, If the keystrokes come with a higher speed, one might redirect the input to a special field. Like scanning an ISBN without targeting the input field first.

I have an interface for COM for DATALOGIC - but as long as the scanner provides a serial (aka USB) interface, it works with any. Here a background objects waits for the serial input hand handles the input. Logically it is independent of special headers.
Not every scanner can do that, and we skipped the scenario because customer runs VFP on a Terminal Server and we found no way to hand the USB signals from local to the remote server.

Some cheap China are just keyboard - but scan runs like a charm.

Just let me know if you need further help
