Technique for information processing device

An information processing device having an operating system installed therein, the operating system including a share function for controlling data transfer between a share source application and a share destination application, the information processing device comprising:

• a communication interface configured to perform a communication with a print intermediation server and a printer, the print intermediation server comprising a storage unit;
• a display unit;
• a processor;
• and
• a memory storing computer-readable instructions as at least a part of the share destination application executed in the information processing device, the computer-readable instructions, when executed by the processor, causing the information processing device to perform:
• receiving, from the share source application via the share function of the installed operating system, property information indicating a property of a particular file identified by the share source application;
• generating, based on the property information, a unique character string unique to the particular file;
• sending, to the print intermediation server via the communication interface, the particular file and the unique character string associated with the particular file such that the unique character string and the particular file are stored in association with each other in the storage unit of the print intermediation server;
• receiving, from the print intermediation server via the communication interface, M pieces of unique character strings stored in the print intermediation server, the M being an integer equal to 2 or more;
• causing the display unit to display a first selection screen, the first selection screen being for causing a user to select a first unique character string from among the M pieces of unique character strings;
• and
• sending, to the printer via the communication interface, a print instruction including the first unique character string selected via the first selection screen, the first unique character string being used by the printer which received the print instruction in order to acquire print data of the particular file associated with the first unique character string and perform printing based on the acquired print data.

A method for controlling an information processing device having an operating system installed therein, the operating system including a share function for controlling data transfer between a share source application and a share destination application, the information processing device comprising:

• a processor;
• a communication interface configured to perform a communication with a print intermediation server and a printer, the print intermediation server comprising a storage unit;
• and a display unit, the method comprising:
• receiving by the processor, from the share source application via the share function of the installed operating system, property information indicating a property of a particular file identified by the share source application;
• generating by the processor, based on the property information, a unique character string unique to the particular file;
• sending by the processor, to the print intermediation server via the communication interface, the particular file and the unique character string associated with the particular file such that the unique character string and the particular file are stored in association with each other in the storage unit of the print intermediation server;
• receiving by the processor, from the print intermediation server via the communication interface, M pieces of unique character strings stored in the print intermediation server, the M being an integer equal to 2 or more;
• causing by the processor the display unit to display a first selection screen, the first selection screen being for causing a user to select a first unique character string from among the M pieces of unique character strings;
• and
• sending by the processor, to the printer via the communication interface, a print instruction including the first unique character string selected via the first selection screen, the first unique character string being used by the printer which received the print instruction in order to acquire print data of the particular file associated with the first unique character string and perform printing based on the acquired print data.
