Abstract: A hybrid printer includes at least one impact type print head and at least one non-impact type print head, which are selectively used to print not only graphic information but also character information. For example, the impact type print head may be a type wheel print head and the non-impact type print head may be a pen print head. The print heads are selectively magnetically coupled to the carriage drive belt.

Abstract: A color image processing system having an under color removal (UCR) function is provided. A mode set switch is preferably provided to set the UCR function to be operative or inoperative selectively. An UCR rate setting unit is preferably provided so as to varyingly set the UCR to be applied to color image data. Data of four color components, including cyan, magenta, yellow and black, are processed. In the preferred embodiment, the three color components other than black are processed and printed first, and, then, a black component image is printed at the end.

Abstract: A method and system for semiautomatically setting a sheet of paper in a typewriter, printer and the like is provided. In accordance with the present invention, when a manually operable auto-set lever is moved from a first setting position to a second setting position, pressure and bail rollers are moved away from a platen roller around which a sheet of paper is to be set. At the same time, a carriage is moved to a first predetermined position of its travelling path. After inserting the leading edge of the sheet, when the auto-set lever is returned to the first setting position from the second setting position, the platen roller is driven to rotate with the pressure rollers in pressure contact therewith to advance the sheet over a predetermined distance along its line-feed direction and thereafter the carriage is moved to a second predetermined position during which the bail rollers are moved to press the sheet against the platen roller thereby setting the sheet ready for typing or printing.

Abstract: A CRT display screen of a word processor apparatus displays at least one line of characters. The number of characters in the line is variable, and the character size is automatically adjusted so that the lines fill the width of the screen regardless of the number of characters. The number of characters may be selected from several predetermined numbers such as 80, 96, 128 etc. Alternatively, the number of characters may be determined by the right margin position. In the latter case, when the right margin position is leftward of a predetermined character position, such as 80, the characters may be displayed in 80 character line format with blank spaces rightward of the right margin.
