5. The image forming apparatus according to claim 4 , wherein

if the detection section detects that the second discharging tray is open, the control section executes the print job including printing on the paper that has the size different from the predetermined standard size and discharges the printed paper to the second discharge tray.

6. The image forming apparatus according to claim 1 , further comprising:

a double-sided printing paper conveyance path configured to reverse a printing object for double-sided printing, wherein

if the instructions regarding the print job received in the control panel indicate the print job includes double-sided printing, and if the detection section detects that the second discharging tray is opened, the control section stops the print job and gives an alarm indicating a user should close the second discharging tray.

7. The image forming apparatus according to claim 6 , wherein

if the detection section detects that the second discharging tray is closed, the control section executes the print job including performing the double-sided printing using the double-sided printing paper conveyance path, and discharges the printed paper to the first discharge tray.

8. The image forming apparatus according to claim 1 , wherein the control panel comprises at least one of operation keys and a touch-screen display panel.

9. An image forming method, comprising:

receiving instructions regarding a print job including printing image data to a paper in a printer section;

discharging the printed paper to a first discharging tray or a second discharging tray, the second discharging tray movable between an open position for receiving the discharged paper and a closed position for guiding the paper to the first discharging tray;

detecting whether the second discharging tray is in the open or closed position; and

controlling execution of the print job including controlling the printer section and discharge of the printed paper to one of the first discharging tray and the second discharging tray, based on the instructions received and whether the second discharging tray is detected in the open or closed position.

10. The method according to claim 9 , wherein

if the received instructions regarding the print job indicate the print job includes a stapling operation, and if the second discharging tray is detected in the open position, the print job is stopped and an alarm is provided indicating a user should close the second discharging tray.

11. The method according to claim 10 , wherein

if the second discharging tray is detected in the closed position, the print job including the stapling operation is executed and discharged to the first discharging tray.

12. The method according to claim 9 , wherein

if the received instructions regarding the print job indicate the print job includes printing on a paper that has a size different from a predetermined standard size, and if the second discharging tray is detected in the closed position, the print job is stopped and an alarm is provided indicating a user should open the second discharging tray.

13. The method according to claim 12 , wherein

if the second discharging tray is detected in the open position, the print job including printing on the paper that has the size different from the predetermined standard size is executed and discharged to the second discharging tray.

14. The method according to claim 9 , wherein

if the received instructions regarding the print job indicate the print job includes double-sided printing, and if the second discharging tray is detected in the open position, the print job is stopped and an alarm is provided indicating a user should close the second discharging tray.

15. The method according to claim 14 , wherein

if the second discharging tray is detected in the closed position, the print job including double-sided printing is executed and discharged to the first discharging tray.

16. A non-transitory computer-readable medium containing instructions for controlling an image forming apparatus comprising a printer section configured to print image data to a paper according to a print job, a control panel configured to receive instructions regarding the print job, a first discharging tray configured to receive the printed paper, and an second discharging tray movable between an open position for receiving the discharged paper and a closed position for guiding the paper to the first discharging tray, the instructions causing a control section to:

detect whether the second discharging tray is in the open or closed position; and

control execution of the print job including controlling the printer section and discharge the printed paper to one of the first discharging tray and the second discharging tray, based on the instructions received and whether the second discharging tray is detected in the open or closed position.

17. The non-transitory computer-readable medium according to claim 16 , wherein

if the received instructions regarding the print job indicate the print job includes one of a stapling operation or a double-sided printing, and if the second discharging tray is detected in the open position, the instructions further cause the control section to stop the print job and provide an alarm indicating a user should close the second discharging tray.

18. The non-transitory computer-readable medium according to claim 17 , wherein

if the second discharging tray is detected in the closed position, the instructions further cause the control section to execute the print job including the stapling operation or the double-sided printing and discharge the printed paper to the first discharging tray.
