Disclosed are a communication apparatus capable of efficiently using a communication line, a control method of the communication apparatus, a facsimile apparatus, a communication method, and a program. To accomplish this, if "print later" in a menu is selected with an image displayed during data communication while a line is connected (S432), printing data is generated from an HTML file of the displayed image (S433). That is, the displayed image is designated as an image to be printed after the line is disconnected. The generated printing data is stored in a printing data buffer (S434). If the presence of the data in the printing buffer is detected (S437) after the line is disconnected (S436), the data is printed (S438).
