Installer package and information processing apparatus

An installer package including an installer program for an information processing apparatus configured to communicate with an image processing device of a particular model, the information processing apparatus, comprising:

• a storage;
• and
• a controller,
• the storage storing a first driver, first driver information, and first port information;
• the first driver configured to control the image processing device of the particular model;
• the first driver information identifying the first driver and including model identification information that identifies the particular model of the image processing device;
• the first port information identifying a name of a port that the image processing device uses to communicate with the information processing apparatus;
• and
• the controller configured to execute the installer program of the installer package,
• the installer package comprising:
• a second driver for a particular function;
• an executable file including the installer program;
• and
• a reference table;
• wherein the installer program, when executed by the controller, causes the information processing apparatus to perform:
• obtaining the first driver information from the storage;
• obtaining the first port information corresponding to the obtained first driver information from the storage;
• determining whether the model identification information of the obtained first driver information is included in the reference table;
• and
• based on determining that the model identification information of the obtained first driver information is included in the reference table, installing the second driver in the storage, thereby storing the second driver, second driver information that identifies the second driver, the model identification information that identifies the particular model of the image processing device, and the first port information, in the storage in association with each other.
