Computer-Readable Storage Medium and Printing System

A printing system comprising an information processing apparatus and a printer, the information processing apparatus and the printer being configured to communicate with each other in conformity with a predetermined communication protocol, the printing system comprising channels configured to cause the printer to print an image based on image data, the channels including:

• a first channel configured to cause the information processing apparatus to conduct a first rasterization process to generate first rasterized data, and cause the printer to receive the first rasterized data and print an image based on the first rasterized data;
• and
• a second channel configured to cause the printer to conduct a second rasterization process to generate second rasterized data and print the image based on the second rasterized data,
• wherein the information processing apparatus is configured to:
• display a setting screen, the setting screen being configured to accept entry of print settings applicable to the printer, the print settings including a first special setting, the first special setting being feasible to the first channel but infeasible to the second channel;
• and
• in response to a specific operation to the setting screen, the specific operation being an operation related to the first special setting, determine the first channel to be a processing channel to be used to cause the printer to print the image.
