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.
