Printing system, and set and computer-readable medium therefor

A set comprising:

• a printer;
• and
• a non-transitory computer-readable medium storing computer-readable instructions that are executable by a computer coupled with a first communication interface and a memory, the instructions being configured to, when executed by the computer, cause the computer to perform:
• a determining process of determining whether to instruct the printer to start a pre-printing operation based on preparation instruction information, the determining process comprising:
• when there is not information stored in a queue area of the memory, determining to instruct the printer to start the pre-printing operation;
• and
• when there is information stored in the queue area, determining not to instruct the printer to start the pre-printing operation, the pre-printing operation being an operation to be performed by the printer to record an image with particular quality on a sheet in a printing operation, the preparation instruction information being information to be transmitted to the printer in advance of an instruction to cause the printer to perform the printing operation, the queue area being configured to store one or more pieces of information to be transmitted to the printer via the first communication interface, with a transmission sequence being specified for the one or more pieces of information;
• a preparation instruction process in response to determining to instruct the printer to start the pre-printing operation, the preparation instruction process comprising storing the preparation instruction information into the queue area;
• a generating process in response to determining to instruct the printer to start the pre-printing operation and performing the preparation instruction process, the generating process comprising generating print data based on specified contents data;
• and
• a print instruction process comprising storing print instruction information into the queue area, the print instruction information being for instructing the printer to perform the printing operation based on the generated print data,
• wherein the printer is configured to perform the pre-printing operation and the printing operation, the printer comprising:
• a second communication interface;
• and
• a controller configured to perform:
• a preparation instruction receiving process comprising receiving the preparation instruction information from the computer via the second communication interface;
• a pre-printing process in response to receiving the preparation instruction information, the pre-printing process comprising controlling the printer to perform the pre-printing operation;
• a print instruction receiving process comprising receiving the print instruction information from the computer via the second communication interface;
• and
• a print process in response to receiving the print instruction information and terminating the pre-printing process, the print process comprising controlling the printer to perform the printing operation in accordance with the print instruction information.

A non-transitory computer-readable medium storing computer-readable instructions that are executable by a processor coupled with an information processing device comprising a communication interface and a memory, the instructions being configured to, when executed by the processor, cause the processor to perform:

• a first determining process of determining whether to instruct a printer to start a pre-printing operation based on preparation instruction information, the first determining process comprising:
• when there is not particular information stored in a queue area of the memory, determining to instruct the printer to start the pre-printing operation;
• and
• when there is particular information stored in the queue area, determining not to instruct the printer to start the pre-printing operation, wherein the pre-printing operation is an operation to be performed by the printer to record an image with particular quality on a sheet in a printing operation, the preparation instruction information is information to be transmitted to the printer in advance of an instruction to cause the printer to perform the printing operation, and the queue area is configured to store one or more pieces of information to be transmitted by an operating system of the information processing device to the printer via the communication interface, with a transmission sequence being specified for the one or more pieces of information;
• a preparation instruction process in response to determining to instruct the printer to start the pre-printing operation, the preparation instruction process comprising storing the preparation instruction information into the queue area;
• a generating process in response to determining to instruct the printer to start the pre-printing operation and performing the preparation instruction process, the generating process comprising generating print data based on specified contents data;
• and
• a print instruction process comprising storing print instruction information into the queue area, the print instruction information being for instructing the printer to perform the printing operation based on the generated print data.
