  • the operation window 2600 may be popup-displayed before output of a print job stops, that is, when the stack tray of the large-volume stacker becomes almost fully loaded.
  • the control unit 205 popup-displays the operation window 2600 when the stack tray of the large-volume stacker becomes almost fully loaded. If the user selects another delivery destination before the stack tray of the large-volume stacker becomes fully loaded, the controller unit continues output of the print job by switching the delivery destination without stopping the output when the stack tray of the large-volume stacker becomes fully loaded.
  • the operation window 2600 may provide a display 2604 representing the remaining number of output sheets of the print job so that the user can easily determine whether to select another delivery destination or whether to cancel the full load state of the stack tray and output printed materials again to the stack tray.
  • the operation window 2600 may provide a key 2605 to print another job so as to output another job while the user takes out sheets from the stack tray and sets another vacant dolly.
  • the control unit 205 detects that the user has pressed the key 2605 , it searches queued jobs for a job requiring a delivery destination other than the stack tray of the large-volume stacker. Then, the control unit 205 prints out the job to the delivery destination other than the stack tray of the large-volume stacker.
  • control unit 205 may allow the user to confirm the delivery destination of a queued job and select another delivery destination except for the delivery destination of the queued job.
  • the control unit 205 controls the system 1000 so that the printing apparatus 100 can print a succeeding job corresponding to a job requiring a delivery destination different from the stacker.
  • the control unit 205 controls the system 1000 to output the printed materials of the succeeding job from the printing apparatus 100 to the destination of a succeeding sheet processing apparatus via the straight path (see FIG. 4 ) inside the stacker 200 a even while the front door is kept open.
  • control unit 205 can cause the printing apparatus 100 to execute printing of a succeeding job while suspending printing of a job which inhibits the use of the tandem function. This can increase the productivity of all jobs even when no tandem function is used.
  • the control unit 205 displays a stacker output ready window 2800 illustrated in FIG. 23 at one of the following timings during output to another delivery destination after the stack tray of the large-volume stacker becomes fully loaded with outputs.
  • the stacker output ready window 2800 has a key 2801 to return output to the stacker, and a key 2802 to keep output to the tray.
  • control unit 205 When the control unit 205 detects that the user has pressed the key 2801 , it closes the stacker output ready window 2800 . At the same time, the control unit 205 switches the delivery destination of the print job to the stack tray of the large-volume stacker, and outputs the print job.
  • control unit 205 Upon detecting that the user has pressed the key 2802 , the control unit 205 only closes the stacker output ready window 2800 without switching the delivery destination of the print job to the stack tray of the large-volume stacker.
  • the stacker output ready window 2800 may display the total number of output sheets of the print job or the number of printed sheets when the full load state of the stack tray is canceled. From this display, the user can easily determine whether to return output to the stack tray of the large-volume stacker, or keep output to another delivery destination other than the stack tray of the large-volume stacker.
  • control unit 205 When the control unit 205 detects that the stack tray of the large-volume stacker becomes fully loaded with outputs and its full load state is canceled during output to another delivery destination, it determines the remaining number of output sheets of the print job. If the control unit 205 determines that the remaining number of output sheets of the print job is larger than the number of sheets, held in the RAM 208 or HDD 209 , which are to be output again to the stack tray of the large-volume stacker, it returns the destination of the print job to the stack tray of the large-volume stacker.
  • control unit 205 determines that the remaining number of sheets of the print job is smaller than the number of sheets which are to be output again to the stack tray of the large-volume stacker, it keeps output to another delivery destination without returning the destination of the print job to the stack tray of the large-volume stacker.
  • the number of sheets which are to be output again to the stack tray of the large-volume stacker may be set in the user mode or designated together with a job.
  • the large-volume stacker To make the delivery tray empty, the large-volume stacker must execute the following operation until the operator takes out sheets from the stack tray and sets an empty dolly. This operation is more cumbersome and takes a longer time than an operation to remove output sheets from the tray of the saddle stitching apparatus. This operation is an operation to lift down the stack tray, open the door, extract the dolly, set an empty dolly, close the door, and lift up the stack tray.
  • the print operation can continue even while sheets are taken out from the stack tray of the large-volume stacker, increasing the productivity.
  • post-processing is determined in accordance with the number of dollies possessed by the user or for each large-volume stacker.
  • One print job is output using the stack tray of only one large-volume stacker.
  • the stack trays of large-volume stackers can be switched and used for one print job. By this switching, the printing system 1000 can flexibly deal with the use of large-volume stackers in accordance with the user environment.
  • the operator need not exchange dollies, increasing both productivity and operability.
  • the user can designate a delivery tray used for alternate output when the stack tray of the large-volume stacker becomes fully loaded.
  • the user can always recognize the destination of output materials during alternate output.
  • the user can select whether to continue output to the alternate destination or return output to the stack tray of the large-volume stacker when an empty dolly is set during alternate output.
  • the user can make determination without impairing productivity and operability.
  • a computer may achieve the functions shown in the drawings in the embodiment in accordance with an externally installed program.
