If you produce documents for anyone other than yourself—clients, regulators, professors, or publishers—you need a professional PDF printer. Download PDF-XChange Editor (free tier) or doPDF. Spend ten minutes configuring the default save location and compression settings.

Use Microsoft for speed, use a third-party for safety.

After install, go to Settings > Bluetooth & devices > Printers & scanners. Find your new PDF printer. Click "Manage" > "Printing preferences." This is where the magic happens. Set your default resolution (300 DPI is standard; 600 DPI for text) and default save location.
