Abstract: A multi-function unit includes a printer engine, a logical copying machine carrying out a copying process with respect to a recording medium by the printer engine, and a plurality of logical printers carrying out printing processes with respect to the recording medium by the printer engine. The logical copying machine and the logical printers carry out apparent parallel operations.

Abstract: A high-speed network printer apparatus which can be used in common by clients having different communication protocols and which can sort out printing jobs into the order of clients. Printing information is supplied from a client which may be a personal computer or a work station through a connector of the printer apparatus. A LAN interface driver receives the printing information and identifies a communication protocol by which the printing information is transferred. A communication protocol controller receives printing information in accordance with a predetermined protocol. A spooling controller, which is coupled to a storage unit which stores the received printing information, creates a queue for printing jobs. A printer controller reads out from the storage unit the printing information corresponding to a printing job of the highest priority which is designated by the queue, and forms a dot image on the basis of the printing information. A printing mechanism prints the image on paper.

Abstract: A character resource utilizing system for preparing print data from an extracted character resource and printing characters. The character resource utilizing system includes a memory for storing a first type of character resources and a second type of character resources, a print data processing unit for reading a desired character resource from the memory and preparing print data, a printing mechanism for printing the print data, and a processing unit for performing a charging process in accordance with the use of the second type of character resources read from the memory. Another character resource utilizing system comprises a character resource managing apparatus for storing at least a second type of character resources and transferring the second type of character resources in response to a character resource request, and a printing apparatus including the aforementioned memory, print data processing unit, printing mechanism and processing unit.
