Thanks! print() with content used inside setup and draw works as expected in firefox, and other browsers. So we want to keep the code as is, because we do want to invoke the print dialog if there's no content. The remaining todo on #4272 is to see if we can use the friendly error system to detect a pattern of print("content") outside of setup and draw.
