Thanks, Framers, for great explanations and resources. I have now set the Adobe PDF default printer and unchecked that system fonts box in both locations. Note: The box remained unchecked in Frame's Print Setup dialog when I booted up this morning, and even when I switched to and from a physical printer. Yay!
But I can't rely on printing only from PDF. --Without changing settings, a PDF often prints slightly smaller than the original. That's insignificant for most users of the finished PDF. But when type is already at 7 point, any smaller makes reading/proofing even more difficult. If I want to check a measurement, that inadvertent reduction might make it incorrect. Changing settings takes more time than using a physical printer. --While distilling runs much more smoothly these days than it used to, I don't always want to take the time for those extra steps just to get a hard copy. --PDF conversion mangles some obscure formulas/symbols no matter what work-arounds I employ. I need to see them correct at least once--my physical printer has no problem with them. (But who knows, maybe the font box issue will resolve that, too!) --My physical printer works perfectly for me in every other instance. Plus it has stunning output that is slightly reduced in quality if I print from the PDF. Again, most people wouldn't notice, but I do. Thanks again everyone, Karen
