Printing system and method of controlling printing system that allow a user of a mobile terminal to print to an image forming apparatus using the mobile terminal, and a service provider to charge the user for printing

A printing system in which a mobile terminal and a plurality of image forming apparatuses are connectable to a management system and a charging system via a network, wherein the management system comprises at least one memory that stores instructions, and at least one processor configured to execute the instructions to function as:

• (a) an authentication unit configured to authenticate that a user of the mobile terminal is a registered user of the printing system;
• (b) a search unit configured to search for one or more image forming apparatuses, out of the plurality of image forming apparatuses, in accordance with a search condition input in the mobile terminal;
• (c) an issuance unit configured to issue a print job including information by which a print instruction to an image forming apparatus, which is selected as a printing target can be identified;
• and
• (d) a requesting unit configured to request clearance processing based on charge information to the charging system after outputting of a printed material by the selected image forming apparatus,
• wherein the charging system for charging payment for a print service provided using an image forming apparatus, of the plurality of image forming apparatuses, by one or more service providers, comprises at least one memory that stores instructions, and at least one processor configured to execute the instructions to function as:
• (a) a confirmation unit configured to confirm that the clearance processing for the user of the mobile terminal is possible;
• and
• (b) an execution unit configured to execute the clearance processing in accordance with the request from the management system,
• wherein the mobile terminal comprises at least one memory that stores instructions, and at least one processor configured to execute the instructions to function as:
• (a) a display unit configured to display (i) a setting region, on a screen, for inputting a print setting for print data, and a search region for inputting a search condition for image forming apparatus candidates, of the plurality of image forming apparatuses, for executing printing, and (ii) display content that associates information of the one or more image forming apparatuses, searched for by the search unit of the management system, with charge information for when the print data is printed, by the print setting, on the one or more image forming apparatuses, respectively, on a screen that includes a selection region by which it is possible to select a printing target, out of the one or more image forming apparatuses, wherein the charge information is calculated based on at least (i) cost fees according to the respective image forming apparatuses that are necessary if the print data is printed, obtained by the print setting, and (ii) an additional fee required by a service provider, of the one or more service providers, of the respective image forming apparatuses;
• and
• (b) a transmission unit configured to transmit, to the management system, a print instruction that includes information of an image forming apparatus selected as the printing target in the selection region, and
• wherein each the image forming apparatus, of the plurality of image forming apparatuses, comprises a printer configured to output printed material by printing the print data based on the issued print job when the image forming apparatus is selected as the target of the printing.
