When I try to print from the editor view with XML Editor 18.0, build 2016042012 and java.runtime.version 1.8.0_72-b15 on OS X El Capitan Version 10.11.5 (15F34), I get a "no print service found" error message. The on-line <oXygen/> discussion logs show reports of similar behavior under Linux from 2005 and 2006, but I don't understand the explanations, which require a greater familiarity with the operating system than I have. I would be grateful if someone could please explain in end-user language how I can make <oXygen/> aware of my printer.
