  • Multiple Font Management System And Method
    Publication number: 20090284778
    Abstract: A multiple font management system and method in a printing device for activating multiple fonts is provided for enabling base font localization and font patching for print jobs to reduce the need to upload entire fonts in order to provide localized receipts or to provide corrections to partially-corrupted font tables. A font access level stores locations of activated base, localization and patch fonts and are referenced in an access order during character retrieval so as to apply retrieval priority to patches and localizations. A font storage level maintains multiple tier character indices for referencing character shape data in order to provide faster character searching through each of the multiple activated fonts than a single-level index.
