Abstract
An output interface allows a user circuit to access data for multiple objects in an interleaved fashion. Status information is provided to guarantee data availability before each transfer sequence is started. An identifier is provided for each object. Each identifier, after data transfer has ended, may be subsequently reused to identify a different object. The interface provides the ability to retrieve all data in an object or to cancel the object before reaching the end and discarding the unretrieved data. The objects are provided to the appropriate processing mechanisms within the printer to implement a printing task. These objects correspond to images and text to be printed on a page. Object data is temporarily stored in limited data memory of the memory system and object headers are stored in header memory before transfer via the output interface. Each object to be printed has an object header and may, or may not, have associated object data.
