Abstract
An image processing apparatus for outputting a page image corresponding to print data inputted from an external source has an analyzer for analyzing the print data at the time of outputting the first copy and generating a page image, an image spooler for holding the page image at the time of outputting the first copy, and a page image reading unit for reading out the spooled page image at the time of outputting the second and subsequent copies. Whether the image spooler and the page image reading unit are used or not is discriminated in accordance with the maximum number of sorting page images which can be processed at once by a mechanical sorter and the designated number of print copies.
Claims10
An image processing apparatus for outputting a page image corresponding to print data inputted from an external source, comprising:
- analyzing means for analyzing said print data at the time of outputting a first copy and generating a page image;
- image spooling means for holding said page image at the time of outputting the first copy;
- page image reading means for reading out said spooled page image at the time of outputting second and subsequent copies;
- mechanical sorting means for performing mechanical sorting and paper ejection every copy;
- discriminating means for discriminating whether said mechanical sorting means can be used or not and discriminating the maximum number of sorting page images which can be processed at once by said mechanical sorting means;
- and
- switching means for, when a plural copy print is designated, discriminating whether to execute the plural copy print by using said image spooling means and said page image reading means, or to execute the plural copy print without using said image spooling means and said page image reading means, in accordance with a discrimination result of said discriminating means and the designated number of copies.
An image processing method of outputting a page image corresponding to print data inputted from an external source, comprising:
- an analyzing step of analyzing said print data at the time of outputting a first copy and generating a page image;
- an image spool step of holding said page image at the time of outputting the first copy;
- a page image reading step of reading out said spooled page image at the time of outputting second and subsequent copies;
- a discriminating step of discriminating the maximum number of sorting page images which can be processed at once by mechanical sorting means for performing a mechanical sort paper ejection every copy;
- and
- a determining step of determining whether to execute a plural copy print using said page image reading step, or to execute the plural copy print without using said page image reading step, in accordance with a discrimination result in said discriminating step and the designated number of print copies.
A computer-readable medium which stores a program for executing an image processing method of outputting a page image corresponding to print data inputted from an external source, wherein said program comprises:
- code for executing an analyzing step of analyzing said print data at the time of outputting a first copy and generating a page image;
- code for executing an image spool step of holding said page image at the time of outputting the first copy;
- code for executing a page image reading step of reading out said spooled page image at the time of outputting second and subsequent copies;
- code for executing a discriminating step of discriminating the maximum number of sorting page images which can be processed at once by mechanical sorting means for performing a mechanical sort paper ejection every copy;
- and
- code for executing a determining step of determining whether to execute a plural copy print using said page image reading step, or to execute the plural copy print without using said page image reading step, in accordance with a discrimination result in said discriminating step and the designated number of print copies.
