Abstract
A font storage management and control arrangement which allows the addition of fonts to font storage and includes a font filter which provides a multilevel control of font information stored, to allow optimum use of limited font storage facilities. As font information is stored to font storage in printer controller, the font characteristics are examined for comparison with a predetermined list of font storage requirements. Font information is stored in accordance with user determination of whether particular font information is useful for the user.

In a print controller for a printer, including an arrangement to print characters in documents transmitted to the controller designated for printing in selected fonts, the selected fonts stored for future use in a device memory, including:
- said device memory including font storage means for storing the selected fonts therein, the selected fonts accessible at the font storage means when required for printing characters designated for printing in the selected fonts;
- external font receipt means, for receiving sets of font information for storage in said font storage means, from a source external to the printer;
- font designation means for designating selected subsets of font information from said font information for storage in said font storage means for future use;
- and
- font comparison means for comparing said selected font information with font information received from said external font receipt means, and forwarding to said font storage means only such selected subsets of font information as are designated at said font designation means.
In a printer, including an arrangement to print characters in documents transmitted thereto in selected fonts, the selected fonts stored and storable for use in a font storage memory with individual members of a set thereof forming said selected fonts accessible when required for printing characters designated for printing in said selected fonts;
- external font receipt means, for receiving font information including selected fonts from a source external to the printer;
- said font information identifying parameters characterizing said font and characters therein;
- and font filter means for filtering from said font information for storage at said font storage means, said font filter means including:
- designating means identifying parameters of font information for storage;
- font comparison means for comparing said font information received from said external font receipt means with identified parameters of font information for storage;
- and
- means for storing in the font storage memory only font information representing a subset of the font member set identified for storage by said font comparison means.
