Patent number: 6515758Abstract: A printer server connectable to a plurality of printers includes a receiver for receiving print data from an external apparatus, a first discrimination unit for discriminating a representation by which the received print data is described, and a selection unit for selecting, from the plurality of printers, a printer to print an image corresponding to the received print data. A second discrimination unit of the printer server discriminates whether the selected printer is capable of processing print data in the discriminated representation. When the selected printer is not capable of processing print data in the discriminated representation, a controller of the printer sever converts the received print data into print data in another representation and transmits the print data in the other representation. The controller transmits print data in the discriminated representation when the selected printer is capable of processing print data in the discriminated representation.Type: GrantFiled: June 7, 1999Date of Patent: February 4, 2003Assignee: Canon Kabushiki KaishaInventors: Toyokazu Uda, Susumu Sugiura, Makoto Takaoka, Shigetada Kobayashi

Patent number: 5617123Abstract: An image processing apparatus for recording image data using an ink jet recording method comprises: an ink jet nozzle to eject an ink droplet and deposit onto a paper; a controller to control the ink jet nozzle so as to enable the recording interval when the ink droplet is deposited on the same position on the paper a plurality of times; a supply circuit to supply image data to the ink jet nozzle; and a distinction circuit to discriminate whether the input image data is a half tone image or a diagram image, wherein this controller controls the recording interval in accordance with the result of the discrimination. With this apparatus, by superposing the recording dots on the same position on the paper in accordance with the binary image data, gradations and graininess can be improved by a simple structure.Type: GrantFiled: June 5, 1995Date of Patent: April 1, 1997Assignee: Canon Kabushiki KaishaInventors: Makoto Takaoka, Susumu Sugiura, Kentaro Matsumoto, Toyokazu Uda, Masami Uda

Patent number: 4860026Abstract: A method for halftone image recording, wherein dots are formed using two or more concentrations of ink, to express different image densities. Each picture element may comprise a plurality of cells, different predetermined members and patterns of which are actually printed in, to express different gradations. Different such patterns may be used for each ink concentration. Several such patterns, using only thin ink, may, for example, be used to express lower densities, several others, using only thick ink, for high densities, and still others, using dots of thin ink and dots of thick ink, for intermediate densities. For color image recording, different concentrations and different members of concentrations can be used for different colors.Type: GrantFiled: June 24, 1988Date of Patent: August 22, 1989Assignee: Canon Kabushiki KaishaInventors: Kentaro Matsumoto, Makoto Takaoka, Masami Fukumoto, Toyokazu Uda, Susumu Sugiura
