I know this topic is old, but seeing how .net is becoming the normal application and having a PC will soon not be required, this would be a super useful. Right now I have spare slave PC that I turn on whenever I need to print labels and use my MacBook to do everything else.
Or instead of LW making their own application, LW could chose to integrate with google cloud print? Many print servers will speak to cloud print negating the need for any computer the run the virtual printer client, and removing the need for LW to maintain it?
Just a thought.
