Abstract: A printing system has fixed print heads in positions that are subject to adjustment between print jobs. The system provides a print preview display that includes a representation of the item of printing stock on which the printing is to be performed. The print preview display also includes a first printing field that is at a location in the representation that corresponds to the position of a first one of the print heads. The print preview display further includes a second printing field that is at a location in the representation that corresponds to the position of a second one of the print heads.

Abstract: A pocket-size check writing device is disclosed with a means for positioning a check form in a writing position having a number of predetermined writing types composed of individual symbol elements and with a manually operable device for actuating the writing type and reproducing the symbols of the writing type such that each writing type is constructed as a mosaic writing head with the symbol elements being independent of one another and individually controllable and being disposed in relating to one another such that they can be assembled in groups for the predetermined writing symbols in such a format that at each writing location one mosaic writing head is immovably disposed and has an arrangement whereby a keyboard reproduces the writing symbols and a control unit is provided which associates individual mosaic writing heads with an appropriate set of keys.

Abstract: In a word processor a string of characters entered serially via a keyboard into a plurality of positions are centered about a particular point on a line of a record medium by providing a storage medium having a plurality of addressed cells which are serially assigned to the positions on the line of the record medium, the cell addresses ranging between first and second values. The cell assigned to the position which includes the particular point receives the first character of the string while all subsequent data characters are considered as pairs of data characters.
