If all of the detected fonts are currently stored in an imaging device, the document is sent to the device. If one or more detected fonts is not stored in the device, the detected glyphs of that font are mapped to a sparse font set. The device is queried to determine whether it can store the sparse font set. If it can, the sparse font set is downloaded to the device. If the device cannot store the sparse font set, the document is converted into a bit-mapped image, which is then imaged.Field of SearchFacsimile memory monitoringMemory interface Coded character INCLUDING CONTROL OF FORMAT AND SELECTION OF TYPE-FACE BY PROGRAMMED CONTROL-SYSTEM (E.G., INPUT TYPEWRITER) Including means for responding to input program or incoming signals and providing output program or signals representing typing operations (e.g., output typewriter) Separate interrelated programs INCLUDING SELECTION OF TYPE-FACE BY PROGRAMMED-CONTROL-SYSTEM OR BY REMOTE CONTROL INCLUDING CONTROL OF FORMAT BY PROGRAMMED-CONTROL-SYSTEM | |
