Print control apparatus and method
First Claim
1. A print control apparatus using a spool file provided by an operating system to temporarily store intermediate data to be outputted in accordance with a print designation of document data, comprising:
- a user interface driver constructed to activate a previewer for displaying image data when receiving a print start event if a preview setting is set; and
a print processor constructed to generate a preview file, to read the temporarily stored intermediate data from the spool file, to cause an image data generator to generate image data from the intermediate data and to save the image data in the preview file, and to inform said previewer of a file identifier of the preview file in response to an image generation request from the previewer activated by said user interface driver,wherein said previewer reads the image data from the preview file based upon the file identifier and displays the image data.

Abstract
This invention is targeted to realize preview displaying by using a system spooler. In the print system according to this invention, when an application program designates printing of a document, document data is spooled into EMF spool file 4. At the same time, previewer 3 is started to transmit a printing image generation request to print processor 5. The print processor 5 reads the data subjected to preview displaying out of the EMF spool file 4, have printer graphic driver 6 generate image data that has an appropriate display size, and informs the name of the image data file to the previewer 8, which then displays the image data.

10. A print control method of controlling an apparatus using a spool file provided by an operating system for temporarily storing intermediate data to be outputted in accordance with a print designation of document data, said method comprising:
-
an activating step of activating previewer for displaying image data when receiving a print start event if a preview setting is set; a processing step of generating a preview file, reading the temporarily stored intermediate data from the spool file, causing an image data generator to generate image data from the intermediate data and to save the image data in the preview file, and informing said previewer of a file identifier of the preview file in response to an image generation request from the previewer activated in said activating step; a step of reading the image data from the preview file based upon the file identifier; and a displaying step of displaying the image data. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A print control program which is stored in a computer readable storage medium and which is executable by a computer operating under an operating system included in the computer, wherein the operating system uses a spool file provided by the operating system for temporarily storing intermediate data to be outputted, said program causing the computer to perform a method comprising:
-
an activating step of activating a previewer for displaying image data when receiving a print start event if preview setting is set; a processing step of generating a preview file, reading the temporarily stored immediate data from the spool file, causing an image data generator to generate image data from the intermediate data and to save the image data in the preview file, and informing said previewer of a file identifier of the preview file in response to an image generation request from the previewer activated in said activating step; a step of reading the image data from the preview file based upon the file identifier; and a displaying step of displaying the image data. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
