How to Find the Mac Address of a Dell Printer

Press Ctrl, Alt, and Del to open the 'Task Manager' program.
Click on the 'File' tab in 'Task Manager' and then open the 'New Task (Run...)' option.
Type in the letters 'cmd' into the box that shows up and then press 'OK' in that box. Another screen, which is black, will show up now.
Type the code 'ipconfig/all' into the black screen and then hit the enter key on your keyboard. This action will reveal all the wireless devices connected to your computer, as well as their MAC addresses. Your Dell printer will be in the list, if it is currently connected to the computer. The MAC address is the number next to 'Physical Address,' which is another name for MAC address (there are many different terms for MAC address).
