padlock symbol/icon dell 948 aio printer

The padlock symbol/icon on the back of your Dell 948 air printer most likely indicates a security slot for a Kensington lock. Kensington locks are physical security devices used to secure a device or equipment to a stationary object such as a desk or table.

With a Kensington lock, you can lock your printer to a desk or table to prevent it from being stolen or moved without your knowledge. The padlock symbol on the printer indicates where you can insert a Kensington lock to secure the printer in place.

Note that not all printers come with a Kensington lock slot, so it's possible that the padlock symbol on your printer may indicate something else. If you're not sure, you can check the user manual for more clarification.
