Not sure this is the best way to go but you can try to add a notes page after each slide and print that with two columns of pages on a paper (see attachment).
Daniel, I'm not finding how to print the slides and notes on two-column pages when I look at the preamble and settings in your .lyx example. I get only the beamer presentation (without notes using \setbeameroption{hide notes} and with notes following each slide using \setbeameroption{show notes}). Please point out what I've missed so I can produce a document with the slides on the left and the notes on the right, as your .pdf attachment shows. Regards, Rich
