If the preference for checking non-embedded fonts is enabled (Edit > Preferences > ARTS PDF Crackerjack X), ARTS PDF Crackerjack X will verify that all fonts in the current document are embedded before printing. If ARTS PDF Crackerjack X finds that a font is not embedded, but that it exists on the current system, it will print normally by including the system font in the output. If the non-embedded font cannot be found on the system, ARTS PDF Crackerjack X will interrupt output to allow you to make a decision on what to do.
