Adapter for communicating with image supply device and printing device and method of controlling the same

摘要

An adapter capable of communicating with an image supply device and an image output device and allowing direct printing even when a plurality of images are transferred at the same time from image supply devices. The adapter transmits a print request associated with a first image to the image output device. If acquisition of a second image is completed before acquisition of the first image completed, the adapter transfers the second image instead of the first image as the image to be printed.
