Abstract: In the print apparatus of this invention, a ruled line is formed on a print medium as a line-up of lines printed by plural printing operation with a line type. A carriage on which the printing unit including the line type is installed is moved from the position where the end of the ruled line composing the outline of a table, is located toward the center of the table at a half print pitch of maximum print pitch, irrespective of the print pitch set by an operator, when the edge of the ruled line is printed. And the ruled line is printed on the print medium by the operation of the printing unit. Moreover, when the middle size of type which can be used corresponding to various print pitches is installed on the carriage, the ruled line can be printed not to protrude from ruled line composing the outline contacting with this ruled line whatever print pitches are set.

Abstract: An electronic apparatus for drawing up documents. The apparatus includes an indicator for indicating registration of information, a keyboard for entering indicia and print pitch information, a memory including a first area for storing keyboard information, a second area for storing entered print pitch information, and a third area for storing registration information according to an indication by the indicator. The apparatus further includes a controller for, in response to the registration indication, storing the indicia information stored in the first area and the pitch information stored in the second area in the third area.

Abstract: An impact printing system which is particularly suitable for word processing is provided with the capability of effecting mid-line pitch changes. The impact printer system which is particularly compatible with interactive display terminals in word processing system has means for receiving a selected one of a plurality of type or character font elements. The pitch of character font elements are different from each other. The printing system includes means for selectively impacting selected characters from selected fonts along lines in a document. The system further includes control apparatus for controlling and determining the selection of font elements to be used and in the case of printing with a particular font element, the characters to be printed in respective positions along the lines of the document to provide the desired document format. The control apparatus includes apparatus for controlling the printing with at least two different font elements having different pitch along a single line.

Abstract: A printing apparatus includes a power supply for supplying power thereto and a battery supply for supplying back-up battery power. A printing mechanism effects printing on a printing paper in accordance with one of a plurality of printing pitches, and a processor controls the printer and produces data signals. A selector selects one of a plurality of printing pitches and applies a signal indicating the selected printing pitch to the processor. A plurality of indicators each indicates a respective one of the plurality of printing pitches and one of the indicators is energized by a data signal produced by the processor. A memory is supplied with back-up battery power by the battery power supply and stores a selected one of the plurality of printing pitches. The memory is accessed by the processor.
