| 9. A method of reading a document page out of a spool file in which document pages created using an application are stored,
and creating bitmap data to be supplied to a printer in correspondence with the read out document page, said method comprising
the steps of:
creating a pattern page in which a pattern is drawn, when it is set to superimpose the pattern in response to an event of
print start, the created pattern page is stored into the spool file;
reading a document page and a pattern page out of the spool file, and making a superimposed page of the read out document
page and the pattern page; and
creating bitmap data in correspondence with the made superimposed page,
wherein in the step of making a superimposed page, a document page is drawn and then a pattern page is drawn when a pattern
is superimposed on a front surface.
