Abstract: A tube connection assembly comprises a male member, a female member and a mating member. The male member is provided with a retaining part that is formed with a non-circular cross-section on the outer peripheral part of a male body. The mating member is held by the retaining part, is formed from an elastic material having a C-shape, and has, on a portion thereof, mating parts. The female member is provided with a receiving part in which the male member is inserted, and mating holes and formed through the receiving part. The mating member is held, so as to prevent rotation, by a base part of a retaining part that has a non-circular cross-section as a part of the outer peripheral part of the male body, and decreases or increases in diameter in the radial direction to mate with the female member through insertion into the mating holes.

The multifunction machine executes, when given a request for a second kind of process, the requested second kind of process without linkage with the server, and, when given a request for a first kind of process, requests the server to execute the first kind of process. The server incorporates a function of executing the first kind of processes that a plurality of multifunction machines request the server to execute. The multifunction machine/server system is constructed of the thus structured server and the plurality of thus structured multifunction machines.

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.

Abstract: Based on both logical information and layout information capable of discriminating a fixed portion of print data from a variable portion of the print data in a process operation of a first page of a printing matter, a printing control system separates the variable portion of the print data from the fixed portion of the print data, and preliminarily registers the print data of the fixed portion into a storage apparatus provided on a printing apparatus. While a process operation for a second page of the printing matter and a process operation for a fixed portion having the same format, to which a printing process operation has been once carried out, are not repeatedly carried out, since only the variable portion of the print data is transmitted to the printing apparatus, both data transfer time for the printing apparatus and printing process time can be shortened.

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.
