Computer-readable storage medium, information processing device, and method for printing composite image

An information processing device comprising:

• a user interface;
• and
• a controller including:
• a processor;
• and
• a non-transitory computer-readable storage medium storing an application program, a general-purpose print program incorporated in advance in an operating system of the information processing device, and computer-readable instructions conforming to a printer connected with the information processing device, the instructions realizing a support program that supports a general-purpose print program incorporated in advance in an operating system of the information processing device and configured to execute driverless printing in cooperation with the support program, the instructions of the support program being configured to, when executed by the processor, cause the controller to:
• when the support program receives a first execution instruction from the general-purpose print program before a print instruction is output from an application program incorporated in the information processing device to the general-purpose print program, obtain, from an external device connected with the information processing device, an image for composition that is registered in the external device, and specify the obtained image for composition as an image for composition to be used for combining with a target image to be printed;
• and
• after specifying the image for composition, in response to the print instruction being output from the application program to the general-purpose print program, receive a second execution instruction from the general-purpose print program;
• and
• in response to receiving the second execution instruction, when print settings corresponding to the print instruction include a particular setting for the printer to print a composite image, cause the user interface to display the composite image in which the target image to be printed according to the received second execution instruction is combined with the specified image for composition obtained from the external device, before performing a printing process to cause the printer to print the composite image displayed on the user interface.

A method implementable by a processor executing computer-readable instructions on an information processing device, the instructions conforming to a printer connected with the information processing device and realizing a support program that supports a general-purpose print program incorporated in advance in an operating system of the information processing device and configured to execute driverless printing in cooperation with the support program, the instructions of the support program being configured to, when executed by the processor, cause the information processing device to execute the method comprising:

• when the support program receives a first execution instruction from the general-purpose print program before a print instruction is output from an application program incorporated in the information processing device to the general-purpose print program, obtaining, from an external device connected with the information processing device, an image for composition that is registered in the external device, and specify the obtained image for composition as an image for composition to be used for combining with a target image to be printed;
• after specifying the image for composition, in response to the print instruction being output from the application program incorporated in the information processing device to the general-purpose print program, receiving a second execution instruction from the general-purpose print program;
• and
• in response to receiving the second execution instruction, when print settings corresponding to the print instruction include a particular setting for the printer to print a composite image, causing a user interface to display the composite image in which the target image to be printed according to the received second execution instruction is combined with the specified image for composition obtained from the external device, before performing a printing process to cause the printer to print the composite image displayed on the user interface.
