PROBLEM TO BE SOLVED: To estimate a printing processing time at a high precision without increasing the load for the printing processing when the printing is performed. SOLUTION: Document file information, which is generated every time when a document is prepared, is read by a document accumulating means 1, and accumulated. A drawn shape extracting means 2 converts the document file information accumulated in the document accumulating means 1 into the information which is required for a processing at a display processing means 3, and the display processing means 3 performs a normal display processing wherein a drawing processing is performed while adjusting to the device characteristics of a display device. At the same time, the drawn shape extracting means 2 extracts basic elements required for the drawing processing by a printing device from the accumulated document file information, and forms an extracted file information, and a pre-treatment for a printing wherein the extracted file information is related to the document file information which is the source of the extraction, and accumulates it in the document accumulating means 1, is performed. When a printing is demanded, a printing time estimating means 4 estimates the required time for printing by the extracted file information, and a printing processing is performed. |
