Printing system, sheet processing method in the printing system, and storage medium

Abstract

A sheet processing method in a printing system constituted by a sheet processing apparatus including a plurality of paper discharge trays having different sheet stacking capacities, to any of whose paper discharge trays a printed sheet is discharged, and a printing apparatus includes setting which of the paper discharge trays is used first for discharging the sheet, specifying the number of remaining pages of sheets to be discharged by a job to be executed, and executing control for discharging the sheets starting from a paper discharge tray different from the set paper discharge tray according to the specified number of remaining pages and a restriction on a stacking amount on each paper discharge tray.

1 . A printing system constituted by a sheet processing apparatus including a plurality of paper discharge trays having different sheet stacking capacities, to any of whose paper discharge trays a printed sheet is discharged, and a printing apparatus, the printing system comprising:
 a setting unit configured to set which of the paper discharge trays is used first for discharging the sheet;   a specifying unit configured to specify the number of remaining pages of sheets to be discharged by a job to be executed; and   a control unit configured to execute control for discharging the sheets starting from a paper discharge tray different from the paper discharge tray set by the setting unit according to the number of remaining pages that is calculated and specified by the specifying unit and a restriction on a stacking amount on each paper discharge tray.   
     
     
         2 . The printing system according to  claim 1 , wherein the paper discharge tray is configured to be able to move to a location of a sheet discharge port. 
     
     
         3 . The printing system according to  claim 1 , wherein the setting unit is configured to set which of the paper discharge trays is used first for discharging the sheets according to a type of the job. 
     
     
         4 . The printing system according to  claim 1 , wherein the control unit is configured to execute control for discharging the sheets starting from the paper discharge tray different from the paper discharge tray set by the setting unit and for then discharging the sheets onto the paper discharge tray set by the setting unit according to the number of remaining pages calculated by the specifying unit and the restriction on the stacking amount of each paper discharge tray. 
     
     
         5 . The printing system according to  claim 1 , further comprising:
 a first selecting unit configured to select a sheet discharge destination for discharging sheets for remaining pages before the sheets discharged onto each paper discharge tray is removed,   wherein the control unit is configured to control the sheet discharge destination for discharging the sheet for the remaining pages according to a selection by the first selecting unit.   
     
     
         6 . The printing system according to  claim 1 , further comprising:
 a second selecting unit configured to select whether to discharge sheets for remaining pages by a speed priority mode or by a stacking amount priority mode after the sheets discharged on each paper discharge tray is removed,   wherein the control unit is configured to control the sheet discharge destination for discharging the sheets for the remaining pages according to a selection by the second selecting unit.   
     
     
         7 . A sheet processing method in a printing system constituted by a sheet processing apparatus including a plurality of paper discharge trays having different sheet stacking capacities, to any of whose paper discharge trays a printed sheet is discharged, and a printing apparatus, the sheet processing method comprising:
 setting which of the paper discharge trays is used first for discharging the sheet;   specifying the number of remaining pages of sheets to be discharged by a job to be executed; and   executing control for discharging the sheets starting from a paper discharge tray different from the set paper discharge tray according to the specified number of remaining pages and a restriction on a stacking amount on each paper discharge tray.   
     
     
         8 . A computer readable storage medium for storing a computer program for performing a sheet processing method in a printing system constituted by a sheet processing apparatus including a plurality of paper discharge trays having different sheet stacking capacities, to any of whose paper discharge trays a printed sheet is discharged, and a printing apparatus, the computer program comprising:
 a code to set which of the paper discharge trays is used first for discharging the sheet;   a code to specify the number of remaining pages of sheets to be discharged by a job to be executed; and   a code to execute control for discharging the sheets starting from a paper discharge tray different from the set paper discharge tray according to the specified number of remaining pages and a restriction on a stacking amount on each paper discharge tray.
