PROBLEM TO BE SOLVED: To speed up a printing process using a spooler. SOLUTION: When print data are passed from an application 11 to a spooler 21, a despooler 23 is informed that one page has been spooled at the end of the spooling on condition that the print data are printed forward. The despooler 23 informed of the end of the spooling of one page despools the page and sends a print command to a printer 40. When the print data are printed backward, the spooler informs the despooler that the previous page has been spooled at its end.
