Abstract

A program execution unit of an MFP apparatus does not use a preset priority for each kind of job or a print estimated time with low precision. Instead, the program execution unit controls a print order of pages of print images, which are generated by each job, so as to maximize the operation rate of a print engine. Printed matters, which include pages of respective jobs in a mixed fashion, are sorted according to jobs in a subsequent stage. Thereby, grouping, which is similar to the prior art, is executed, thereby realizing a print control which requires no exceptional operation.

Claims

1. A print processing method for a printer that has a plurality of functions and a plurality of paper output methods and executes print for each of the functions, comprising:

executing, when prints by the plurality of functions are simultaneous/parallel processed, printing of print images, which are created by image processes associated with the respective functions, by calculating a print order on the basis of a time at which each print image is created and a preset print process ratio between the functions;

executing, when the preset print process ratio is altered where necessary during the printing, printing of remaining print images at the time of the alteration by re-calculating the print order on the basis of the altered process ratio; and

sorting paper sheets, on which the printing is effected, according to each of the functions by the plurality of paper output methods.

2. The print processing method according to claim 1, wherein the time at which each print image is created is a time at which a print image of a minimum unit of print is created, the print order is calculated on the basis of the time of creation of the print image which is created in units of one page at a single-side print time, and the print order is calculated on the basis of the time of creation of the print images which are created in units of two pages at a double-side print time.

3. The print processing method according to claim 1, wherein the time at which each print image is created is a time at which a print image is created at each break point of copies when a copy-unit process needs to be executed in units of a plurality of pages, such as a staple process or a book-binding process, and the print order is calculated on the basis of the time of creation.

4. The print processing method according to claim 1, wherein the preset print process ratio is a ratio of a number of pages that are printed per unit time according to each of the functions.

5. The print processing method according to claim 1, wherein a print order determination table for print processes is created using the preset print process ratio, and the print processes of the plurality of functions are executed with reference to the print order determination table for print processes.

6. The print processing method according to claim 1, wherein when the preset print process ratio is altered during the print process, a print completion estimated time and the print process ratio are re-calculated, the print completion estimated time and the print process ratio, which are results of the re-calculation, are displayed, and the displayed print completion estimated time and the print process ratio are determined, thereby altering a ratio of a number of pages that are printed per unit time according to each of the functions.

7. The print processing method according to claim 1, wherein the plurality of paper output methods are methods in which paper output destinations are distributed according to the functions to a plurality of mechanically constructed trays.

8. The print processing method according to claim 1, wherein the plurality of paper output methods are methods in which paper sheets are output together according to each of the functions by turning a direction of output sheets or inserting sheets for sorting.

9. A printer that has a plurality of functions and a plurality of paper output methods and executes print for each of the functions, comprising:

a printing unit which prints a print image that is created by each of the functions;

a setting unit which sets, when prints by the plurality of functions are simultaneous/parallel processed, a print process ratio between the functions, which is used to determine a priority of print processes;

a processing unit which executes a print process by the printing unit, by determining a print order on the basis of the print process ratio between the functions, which is preset by the setting unit, and a time at which each print image according to each function is created;

an altering unit which alters the print order, when the print process ratio is altered by the setting unit where necessary during the print process by the processing unit, by re-calculating the print order on the basis of a number of remaining print images at the time of the alteration and the altered print process ratio; and

a control unit which executes a control to sort paper sheets, which are printed by the printing unit, according to each of the functions by the plurality of paper output methods.

10. A printer that has a plurality of functions and a plurality of paper output methods and executes print for each of the functions, comprising:

printing means for printing a print image that is created by each of the functions;

setting means for setting, when prints by the plurality of functions are simultaneous/parallel processed, a print process ratio between the functions, which is used to determine a priority of print processes;

processing means for executing a print process by the printing means, by determining a print order on the basis of the print process ratio between the functions, which is preset by the setting means, and a time at which each print image according to each function is created;

altering means for altering the print order, when the print process ratio is altered by the setting means where necessary during the print process by the processing means, by re-calculating the print order on the basis of a number of remaining print images at the time of the alteration and the altered print process ratio; and

control means for executing a control to sort paper sheets, which are printed by the printing means, according to each of the functions by the plurality of paper output methods.
