Image forming apparatus that communicates with a portable terminal device, and information processing system

An information processing system comprising:

• a portable terminal device;
• and
• an image forming apparatus, wherein
• the portable terminal device includes:
• a location-information acquiring unit that acquires physical location information about the portable terminal device;
• a first near field communication (NFC) unit that establishes wireless communication with the image forming apparatus by being brought near the image forming apparatus;
• a first short-range communication unit that has a larger wireless communication coverage than a wireless communication coverage of the first NFC unit and establishes wireless communication with the image forming apparatus by using connection setting information received via the first NFC unit;
• a receiving unit that receives, from the image forming apparatus via the first short-range communication unit, function setting information defining whether each setting item of the image forming apparatus is applicable or not, so as to cause the portable terminal device to update setting items, which have been displayed on a printer setting window of the portable terminal device before the first NFC unit establishes the wireless communication with the portable terminal device, such that an unavailable setting item is changed in display;
• and
• a print control unit that transmits an instruction indicating whether to enable or disable print processing control based on the location information to the image forming apparatus via the first short-range communication unit, and
• the image forming apparatus includes:
• a second NFC unit that establishes, when the portable terminal device comes near the second NFC unit, wireless communication with the portable terminal device;
• a second short-range communication unit that has a larger wireless communication coverage than a wireless communication coverage of the second NFC unit and that establishes wireless communication with the portable terminal device by using the connection setting information received via the second NFC unit;
• a data processing unit that receives data transmitted from the portable terminal device via the second short-range communication unit, performs data processing on the data;
• a printer unit that prints out the data processed by the data processing unit;
• a transmitting unit that transmits, to the portable terminal device via the second short-range communication unit, the function setting information, so as to cause the portable terminal device to update setting items, which have been displayed on the printer setting window of the portable terminal device before the second NFC unit establishes the wireless communication with the portable terminal device, such that an unavailable setting item is changed in display;
• and
• a control unit that controls processing performed by at least one of the data processing unit and the printer unit in accordance with the instruction indicating whether to enable or disable print processing control contained in the data received via the second short-range communication unit.
