    摘要: 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. A mailbox stores printed paper into a designated bin. A printing job table is provided in the printer apparatus, in which each row is allotted to one printing job which includes a field for storing an emulation program name. A registering unit judges whether or not there is a another printing job having the same emulation program name to expedite the printing process.

    摘要: A type of display-panel drive circuit that reduces the power rating in the IC section so the circuit can be formed using IC. A level shift circuit converts a signal S2 from high level to low level or from low level to high voltage level V.sub.H and outputs it as S2'. A first transistor XSC connects an output terminal HVO1 to ground when signal S2 is high level. A second transistor XSU remains nonconductive when the output of the level shift circuit is low level but connects an external signal input terminal VSU to output terminal HVO1 when the output of the level shift circuit is at high voltage level V.sub.H. A third transistor XSD connects an external signal input terminal VSD to output terminal HVO1 when signal S3 is low level and signal S3' is high level but remains nonconductive when both S3 and S3' are low level.
