Abstract

PURPOSE:To transmit appropriate plotting data matched with the use of a plotting device by providing a means for changing the content of plotting data so that the content of plotting data is matched with the specification of the plotting device. CONSTITUTION:When plotting data is outputted from one of CAD devices 1 to 3, an analysis part 11 analyzes the name of the CAD device (number) from which a plotting instruction is outputted, a control code, paper to be used, a plotting direction and a reduction scale. A judgement part 12 judges whether the content is matched with the specification of a printer or not. When there is room for selection such as whether or not there are two or more kinds of paper which are set in the printer or whether or not the plotting direction can be changed, for example, if they are judged to be not matched, a plotting data content input part 15 is started and a user is caused to select paper and the like on a CAD device-side. When the plotting direction of the printer cannot be changed, a change part 13 changes the content of plotting data to be matched with the specification of the printer.
