The fonts supplied by PM are loaded automatically when the system is started and are available to any application at any time. They are said to be public fonts. Any font that you define locally has to be loaded before you can use it. If you load a locally defined font using the Install option of the Workplace Font Palette, that font is available to any application in the system, and, therefore is a public font. Some devices provide their own fonts. All device fonts are public fonts.

Any font loaded using GpiLoadFonts from within an application is a private font. A private font is available only to the application that loads it. The file in which you store a locally created font definition can contain more than one font definition. GpiLoadFonts loads a named font file and, therefore, loads all fonts defined in that file. GpiQueryFontFileDescriptions provides the family name and the face name of each font in a locally defined font file. Use this function to determine if a particular file contains the font you want to use before you load it.

To unload a previously loaded private font file, call GpiUnloadFonts. You cannot unload public fonts with this function.

You cannot use private fonts in a document that you want to print using the spooler. If you want to print the document from a printer server, using the PM_Q_STD format, all the fonts used in the document must be installed as public fonts on the server. You can use either public or private fonts if you specify the data format PM_Q_RAW or if you want to print without the spooler.
