Abstract

Abstract A device for printing a document, such as an HTML document, in which data to be incorporated into an output image can be described in the form of reference to an outside source, the device being capable of smooth printing a large document using a small memory. A document structural information manager creates document structural information which describes a structure of document elements, based on a result of analysis on an HTML document carried out by a document analyzer. During asynchronous downloading of substantial data of each document element, should work memory shortage occur, a memory manager unloads substantial data of a document element with a latter order at which to be incorporated into an output among those in the work memory, and saves the unloaded substantial data in an HDD. Thereafter, when data becomes no longer necessary as a result of being printed, the memory manager deletes the data from the work memory and reloads data saved in the HDD back to the work memory.

Claim 4
Dependent Claim 84 words
The image forming device according to claim 1 , further comprising: a secondary storage device; a save controller for saving the display content data of a document element unloaded from the work memory by the unload controller; and a reload controller for acquiring, when display content data of a document element is incorporated into the output image and the display content data is not present in the work memory, the display content data from the secondary storage device to reload to the work memory.
Claim 5
Dependent Claim 83 words
The image forming device according to claim 2 , wherein the document structure manager creates the document structural information which contains information on a size of display content data of each document element loaded to the work memory, and the unload controller determines an order and a position for each document element appearing in the output image, and unloads the display content data, beginning with display content data with a larger size, when two or more document elements appear in a predetermined range.
Claim 6
Dependent Claim 100 words
The image forming device according to claim 1 , comprising: a recorder for recording information indicating a source from which display content data of each document element loaded in the work memory is acquired, in the document structural information; and a reload controller for acquiring again, when display content data of document element is incorporated into the output image and the display content data is not present in the work memory, the display content data from the source of the display content data to reload to the work memory, the source being known with reference to the document structural information.
Claim 7
Dependent Claim 92 words
The image forming device according to claim 5 , wherein the document structure manager records information indicating a period of time necessary in acquisition of display content data of each document element loaded to the work memory, in the document structural information, and the unload controller determines an order and a position for each document element appearing in the output image, and unloads the display content data, beginning with display content data with a shorter period of time necessary in acquisition, when two or more document elements appear in a predetermined range.
Claim 8
Dependent Claim 32 words
The image forming device according to claim 4 , wherein the two or more document elements appearing in a predetermined range are two or more document elements appearing in the same page.
