A printing apparatus and a printing method perform the steps of computing the shift value of each ejection port in accordance with the thermally-expanded width of a print head, dividing the shift value by a nozzle pitch, using the ejection port which number is minimum among ejection ports having the same integer value of the above quotient as a boundary position, using the print data printed at the boundary position as the logical sum between data for two consecutive ejection ports, and printing...

Disclosed are a printing apparatus and a printing method which can prevent a deterioration in printing image quality when printing is executed on a time-division basis while performing scanning continuously with a printer head. In a two-liquid mixing type ink jet printer which performs printing in halftone by mixing a determined amount of ink with a fixed amount of diluent, when printing is executed through interleaving operation by driving on a time-division basis each determination side electr...

There is described a system for producing prints, which includes inputting device to input image data and information corresponding to the image data, a selector to select either a first mode or a second mode and a printer to print images on a recording medium. In the first mode, the system performs inputting operation of the image data and information corresponding to the image data in addition to a print producing operation. While in the second mode, the system performs the print producing ope...

A printing system comprising a data processor, a printer, and an ID code transmitter for allotting an ID code to a data file for distinguishing the data file from others. An input device is mounted on the printer for providing the ID code to the printer before a printing process is executed. The printer executes the printing process in response to the ID code provided thereto and on the basis of the data file to which the ID code has been allotted. The invention is particularly adapted for preve...

A printing apparatus receives print data described by a printer language from a host computer and prints an image of characters and figures on the basis of the print data. The printing apparatus includes a bit map image developing circuit for receiving print data from the host computer through a bidirectional interface and developing the print data into a bit map image, a bit map image transmitter for transmitting the bit map image of one page developed by the bit map image developing circuit to...

While a transfer sheet 3 including a water-soluble base sheet on which a print layer is provided is floated on water, an adhesion is applied after the base sheet is dissolved, thereby to form a semi-fluidal print layer. An object is pressed against the print layer to achieve printing. In this technique, the present printing method and apparatus shorten the warm-up time required for dissolving the base sheet of the transfer sheet 3 to improve the working efficiency, and the transfer sheet 3 is pr...

The temperature of a portion that belongs to a stencil and is located in the vicinity of a portion retaining a printing paste is increased to reduce the viscosity of printing paste that adheres to the portion retaining the printing paste, thereby allowing the printing paste to be easily separated from the retaining portion for the achievement of easy printing on an object on which a print is to be formed.

A printing group for a printing press includes a plate cylinder, a blanket cylinder operatively coupled to the plate cylinder, and a further cylinder operatively coupled to the blanket cylinder. The blanket cylinder includes two end faces, each of which has a conical bearer ring. The further cylinder also includes two end faces, each of which has a conical bearer ring. The conical bearer rings of the blanket cylinder roll onto the conical bearer rings of the further cylinder under pressure.

It is an object of the invention to achieve a printing apparatus and the like that can provide a user with a print control program through an ink container, a printing medium, or a print head. The printing apparatus includes an ink container for containing ink, a printing medium capable of being printed with the ink of the ink container, and a print head for ejecting ink to the printing medium, where at least one of the ink container, the printing medium, and the print head can be attached/remov...

A method of printing an image on a printing portion of a printing paper using a printer so as to eliminate visible margins. The sheet of printing paper is conveyed within the printer by nipping margins of the sheet. After printing, the printing portion is detached from the printing paper along a cut line. Namely, a print having no margins and no nip markings is formed. Therefore, cutting position controlling mechanisms and paper cutting mechanisms as used in conventional printers are not necessa...
