"Save to PDF"

Hello, You can try this : (Mac) Firsty, make sure that when you press Cmd + P, then open in preview, then in the mac's native preview app, go to the top menu and select File>export as pdf, that it works. If not, continue. ''NOTE : only use about:config if you know what you are doing.'' First, go to '''about:config''', press enter, and accept risk and continue. Next, search for '''print_bg''' and if any values for '''print.printer_[Printer_Name].print_bgcolor''' or '''print.printer_[Printer_Name].print_bgimage''' are false, double click them to set them to true. Next, you can also try going into '''about:config''', searching for '''print.prefer_system_dialog''', then set from false to true. After that, try using Cmd+P to get the PDF. Lastly, you can try using a workaround by pressing Cmd + S, and set save format is Web Page, complete or PDF, then save locally. After that, you can try printing again.
