A printer includes a carriage supporting a printing mechanism, a platen for carrying printing paper, a detector for detecting presence of the printing paper on the platen, a device for determining margin and/or tabulator positions in relation to an end of the platen, a central processing unit for determining the distance between the end of the platen and the printing paper in response to the detector to convert the margin and/or tabulator positions into positions determined from the edge of the paper and to control the printing mechanism in response to thus converted positions, and a memory for storing signals representing the margin and/or tabulator positions.
