Encountering a error can be frustrating, but it is ultimately just a communication breakdown between the PDF file and your viewing software. By installing the necessary font packs, utilizing the "Print as Image" workaround, or ensuring proper font embedding during the creation phase, you can ensure your documents look exactly the way they were intended on any screen.
