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.
