Abstract
In order to prevent wasteful power consumption, in various embodiments, advance activation of a printer is avoided in the event of an attack on a particular port if the printer is used in a network environment with a low security strength. For example, according to one embodiment, while a GPIO signal for activating the printer in advance is generated in response to reception of print data, the GPIO assert setting is disabled if a network to which the printer is connected has a low security strength.
