In which mode does a printer act as its own access point for wireless printing?

Wi-Fi Direct Mode is correct because it allows devices, like printers, to connect directly to each other without the need for a traditional wireless access point or network. In this mode, the printer can establish a peer-to-peer connection with a mobile device or computer for wireless printing. This simplifies the printing process, as users can print directly from their devices to the printer without needing to go through a network.

Other modes generally include scenarios that involve connecting multiple devices through a network or an access point. For instance, Network Mode and Infrastructure Mode imply that the printer requires a wireless network to be operational, whereas Bluetooth Mode operates over a different type of connection not typically used for most modern wireless printing solutions. Wi-Fi Direct Mode stands out by providing a straightforward, direct connection for wireless printing tasks, making it a convenient option for users.
