When a printer only provides basic functionality (such as simple printing without duplexing, color management, stapling, or finishing options), this typically indicates that the system is using a generic or basic printer driver rather than the full-featured driver from the printer manufacturer.
Advanced printer features are enabled through manufacturer-specific drivers, which expose all hardware capabilities to the operating system.
Operating systems often install default or class drivers automatically, especially when printers are connected via USB or discovered on a network. While these drivers allow basic printing, they do not include proprietary features such as high-resolution settings, tray selection, finishing units, or secure printing options. Installing the correct driver package from the printer manufacturer ensures full compatibility and unlocks advanced functionality.

Checking the 3G/4G/5G/LTE settings ensures that the phone's cellular data connection is enabled and configured properly, which is necessary for internet access outside of Wi-Fi coverage areas like a parking lot.

Tethering allows a device (such as a smartphone) to share its mobile data connection with other devices through Wi-Fi, Bluetooth, or USB, creating a small private network for internet access.

A coaxial wall jack indicates that the location is wired for cable internet service. Cable internet uses coaxial cabling to deliver high-speed connectivity, making it the most suitable and likely option for this setup.
