PROBLEM TO BE SOLVED: To reduce the switching frequency of plotting attribute by a method wherein a classifying means, classifying data with respect a plotting demand based on the platting attribute, is provided to switch the plotting attribute by the unit of classification of the classifying means and output data with respect to the same classification continuously. SOLUTION: A host computer 3000 is provided with a CPU 1, processing a document based on a document processing program and the like, stored in a ROM 3, to process communication control by a printer controller 8 between a printer 5000 through a predetermined two-way interface 20. Upon putting power supply ON, a printing related module loads a RAM 2 to classify and group plotting data, supplied from an application, based on plotting attribute, such as color, the width of a line and the like, thereafter, automatic classification process of attribute and plotting process, wherein the plotting attribute is switched by the unit of the group, are effected. In this case, a plurality of plotting data, same in the plotting attribute thereof, are outputted continuously while switching the plotting attribute by the unit of the group. |
