Non-transitory computer readable storage medium, information processing device and printing method storing program to support duplex printing

An information processing device comprising a computer,

• wherein an operating system of the information processing device has a general-purpose print program installed in advance in the operating system,
• wherein a support program corresponding to a printer connected to the information processing device and an application program to which a print instruction that causes the printer to print an image via the general-purpose print program is capable of being input are installed in the information processing device, and
• wherein, in a case where the print instruction is output from the application program to cause the printer to execute duplex printing in a job based on the print instruction, the computer, when instructed by the support program, executes:
• acquisition processing of acquiring intermediate print data of the image having a plurality of pages relating to the job from the general-purpose print program;
• rotation processing of executing, for the intermediate print data or rasterized print data rasterized based on the intermediate print data, processing for rotating the image of a page required to be rotated by 180°;
• rearrangement processing of executing, for the intermediate print data or rasterized print data rasterized based on the intermediate print data, processing for rearranging a processing order from a page order to a print order according to a sheet conveying aspect of the printer;
• and
• output processing of outputting the processed rasterized print data relating to the job after the rotation processing and the rearrangement processing such that the processed rasterized print data is transmitted from the information processing device to the printer as a transmission destination.

A printing method of causing a printer to execute printing based on print data generated in an information process device,

• the printer being connected to the information processing device,
• an operating system of the information processing device having a general-purpose print program installed in advance in the operation system,
• a support program corresponding to the printer connected to the information processing device and an application program to which a print instruction that causes the printer to print an image via the general-purpose print program is capable of being input being installed in the information processing device,
• in a case where the print instruction is output from the application program to cause the printer to execute duplex printing in a job based on the print instruction, the printing method, which is executed by the support program, comprising:
• acquiring intermediate print data of the image having a plurality of pages relating to the job from the general-purpose print program;
• executing, for the intermediate print data or rasterized print data rasterized based on the intermediate print data, processing for rotating the image of a page required to be rotated by 180°;
• executing, for the intermediate print data or rasterized print data rasterized based on the intermediate print data, processing for rearranging a processing order from a page order to a print order according to a sheet conveying aspect of the printer;
• and
• outputting processed rasterized print data relating to the job after the image processing and the rearrangement processing such that the processed rasterized print data is transmitted from the information processing device to the printer as a transmission destination.
