Abstract
In case of temporarily spooling an intermediate language by a printer driver, a high speed print can be performed by suppressing a size and the number of holding data. The printer driver adds a tag of each draw object type to information of a draw command received through a DDI function and holds the resultant information into a primary buffer together with attributes such as draw position information, color information, pattern information, and draw logic information. When the information is held into the primary buffer, if there is a draw object which has already been held, if the types and the draw attributes of the draw objects are identical, the draw object is additionally registered into the primary buffer. If one of 'type is different', 'data cannot be fully stored into the primary buffer', “draw attribute changes”, and “page process is completed” is satisfied, a PDF (Page Data File) is generated from the draw object which has already been held in the primary buffer and spooled.
