Image forming apparatus, communication device, and image forming system for printing data received from communication terminal device

A communication device comprising:

• a printing data reception unit which receives from a communication terminal device printing data including printing target data and printing accompanying information of the printing target data;
• an identification information creation unit which creates identification information for identifying the printing data when the printing data reception unit receives the printing data;
• an identification information transmission unit which transmits the identification information created by the identification information creation unit to the communication terminal device that has transmitted the printing data;
• a printing data storage unit which stores the printing data received by the printing data reception unit by associating the printing data with the created identification information;
• a printing unit which handles as a printing target the printing target data included in the printing target data;
• an identification information acceptance unit which accepts input of identification information;
• and
• a controller which reads from the printing data storage unit the printing data associated with the identification information the input of which is accepted in the identification information acceptance unit, and makes the printing unit print the printing target data included in the printing data using a part of the printing accompanying information,
• wherein the communication terminal device is configured to search for a connectable wireless LAN access point so as to communicably connect therewith and to search for the communication device connected through a network to the wireless LAN access point, when an application software of the communication terminal device starts,
• wherein the communication terminal device and the communication device are configured to be automatically detectable mutually with each other by using a predetermined protocol including Simple Network Management Protocol (SNMP) and Bonjour, and
• wherein the printing data reception unit is configured to receive from the communication terminal device only the printing data generated according to a predetermined protocol including Hypertext Transfer Protocol over Secure Socket Layer (HTTPS).

An image forming system which includes a control unit provided in a communication terminal device and an image forming apparatus which can communicate with the communication terminal device, wherein the control unit of the communication terminal device comprises:

• a printing job acceptance unit which accepts input of a printing job from a user;
• a printing target data generation unit which generates printing target data that is a printing target of the printing job in a format suitable for printing in the image forming apparatus;
• and
• a communication unit which transmits to the image forming apparatus printing data including the printing target data and printing accompanying information extracted from the printing job, and
• the image forming apparatus comprises:
• a printing data reception unit which receives from the communication terminal device the printing data including the printing target data and the printing accompanying information of the printing target data;
• an identification information creation unit which creates identification information for identifying the printing data when the printing data reception unit receives the printing data;
