Non-transitory computer readable storage medium storing set of program instructions for transmitting first and second sets of print data

A non-transitory computer readable storage medium storing a set of program instructions installed on and executed by a computer provided in a terminal device configured to be connected to a printer, the set of program instructions comprising:

• performing an operation reception process to receive via an operation interface a print start operation to start printing a plurality of print images which is represented by respective ones of a plurality of sets of print data, each of the plurality of print images being to be printed using a different print medium in the printer, the plurality of sets of print data including a first set of print data and a second set of print data, the first set of print data representing a first print image correlated with a first print medium type, the second set of print data representing a second print image correlated with a second print medium type;
• performing a first data transmission process to transmit the first set of print data to the printer in response to receiving the print start operation in the operation reception process;
• and
• performing a second data transmission process to transmit the second set of print data to the printer, the second print image based on the second set of print data being to be printed after the first print image is printed,
• wherein the second data transmission process is performed before the printer complete printing the first print image.
