There is provided a printing apparatus that can prevent a user from forgetting to set print settings and that can markedly reduce the number of unnecessary prints caused by unsuitable print settings, for example, in a case in which print data such as image data is sent from an image-supplying apparatus to the printing apparatus and in which the printing apparatus prints the print data. The printing apparatus, which receives print data from an image-supplying apparatus and prints the print data, need not start printing image data immediately after the image data is received. An input of print settings is accepted in the printing apparatus, and the image data is printed using the printing settings that have been input.
