Final answer:
The industry standard facilitating direct camera to printer connections is USB (Universal Serial Bus), which is widely used for wired data transfer.
Step-by-step explanation:
The industry standard that enables a camera to connect directly to a printer would be USB (Universal Serial Bus). USB has been a widely adopted standard and is used for connecting various devices, including cameras and printers, to enable direct communication and data transfer. Technologies like Bluetooth and Wi-Fi are primarily used for wireless communication between devices, whereas Near Field Communication (NFC) is used for close-range communication, typically within a few centimeters. However, for a direct, wired connection between a camera and a printer, USB is the standard interface.
