6. The image forming apparatus according to claim 4 , wherein in a case where a preset time has not passed since completion of output of the printing result based on printing data of the different user, the controller causes the accumulation unit to accumulate the printing data received by the reception unit without causing the output unit to output the printing result based on the printing data received by the reception unit.

7. The image forming apparatus according to claim 4 , further comprising:

a user detection unit that detects whether the user is present near the image forming apparatus,

wherein in a case where the user detection unit detects that the different user is present near the image forming apparatus, the controller causes the accumulation unit to accumulate the printing data received by the reception unit without causing the output unit to output the printing result based on the printing data.

8. The image forming apparatus according to claim 1 , wherein the detector detects the distance between the image forming apparatus and the mobile terminal apparatus, based on an intensity of radio waves in wireless communication between the image forming apparatus and the mobile terminal apparatus.

9. An image forming apparatus comprising:

a detector that detects a distance between the image forming apparatus and a mobile terminal apparatus that is located near the image forming apparatus;

a reception unit that receives printing data from the mobile terminal apparatus;

an output unit that outputs, when a specific operation is performed by a user, a printing result based on the printing data received by the reception unit;

a controller that controls, in a case where the printing data received by the reception unit is printing data from the mobile terminal apparatus for which the distance detected by the detector is within a preset range, the output unit to output the printing result without requiring the specific operation by the user;

an accumulation unit that accumulates the printing data received by the reception unit;

a memory that stores histories of a distance between the image forming apparatus and the mobile terminal apparatus, the distance being detected by the detector; and

a determination unit that determines, based on the histories of the distance stored in the memory, whether or not the mobile terminal apparatus is approaching the image forming apparatus by determining a relative position of the mobile terminal apparatus with respect to another mobile terminal apparatus at a time point before the printing data is received and at a time point when the printing data is received,

wherein the output unit outputs the printing result based on the printing data for which an output instruction operation is performed by the user, from among a plurality of pieces of printing data accumulated in the accumulation unit,

wherein the output unit outputs the printing result when the mobile terminal apparatus is determined to be approaching the image forming apparatus even when the another mobile terminal apparatus is within a predetermined adjacent range of the image forming apparatus, and

wherein even in a case where the printing data received by the reception unit is printing data from the mobile terminal apparatus for which the distance detected by the detector is within the preset range, when the determination unit determines, after the output unit starts to output the printing result based on the printing data, that the mobile terminal apparatus is not approaching the image forming apparatus, the controller transmits alert information to the mobile terminal apparatus.
