HP LaserJet CM4540 MFP went offline, won't print via USB, web server won't load either

HP Recommended
LaserJet CM4540 MFP
Microsoft Windows 10 (64-bit)

My HP LaserJet CM4540 randomly went offline recently. I tested my ethernet port in the wall and it is functioning properly. The ethernet port on the printer has a blinking orange light and a solid green light next to it. 

I then tried to access the printer via it's IP address in a web browser and was given minimal information about my printer (host name, system up time, HP Jetdirect version, firmware version, IP and hardware addresses, LAA) and a status of "Device Not Attached". 


I then tried to do a test print directly to a laptop via USB cable and the document gets stuck in queue, throws an error, and then get a Windows error message of a device malfunction and it disables the device. 


And to make matters even more complicated, my control panel is not working and I have only been using a web browser to troubleshoot issues up until now.
