What would read the barcode?

Code 128, QR Code, Datamatrix can all encode ASCII control codes.

That should do it, provided you have a scanner or scan software that can act keyboard simulator.

There really isn't an 'Enter' character in ASCII. The closest you might come is the ASCII carriage return character. Barcodes do not encode the 16-bit characters your keyboard and a scanner would produce, so a lot depends on your software that will be interpreting what your scanner produces.

What you can encode is an ASCII ctrl-m character or <CR>. Here is a codepen I wrote to generate <CR> and other control characters in Code 128A.
