  • Common font rasterizer available to multiple printer personalities
    Patent number: 5572631
    Abstract: A printer that allows a plurality of personalities access to a common rasterizer. The printer is constructed of an operating system, a scaleable font and a personality interface. The scaleable font is logically connected to the operating system as is the personality interface. Additionally, the personality interface is logically connected to the plurality of personalities and the common rasterizer. The personality interface allows the plurality of personalities to communicate with the operating system and the common rasterizer. When the operating system receives a print job, it activates one of the plurality of personalities to become an active personality. Next, the operating system sends the print job through the personality interface to the active personality and gives the active personality exclusive access to the common rasterizer.
