US Patent 7808672 Image forming device and image formation control method

An image forming device for printing a page which incorporates content data acquired from a reference destination, capable of starting printing earlier. A display analyzing section (33) analyzes a printing document and lays out a document element for tentative page dividing. In the laying out, for a document element whose content data needs to be acquired from a reference destination, a tentative size is used and, for a document element having content data of a known rendering size, the rendering size is used. A document manager (45) monitors a state of acquisition of the content data and instructs a rendering section (34), upon detection of completion of acquisition of content data to be laid out on a first page, to render the image of the page.
