Printer unable to init. printer shows LAN ACTIVE

Go to device manager and check for the port setting. Maybe the port driver is corrupted.

Try to uninstall and reinstall the printer software.

Check the lan connection cable by removing the connection and return it back. maybe it is just loose connection.

Try this as well
Go to START MENU
Choose RUN
Type the letter "cmd"
Type the word "net stop spooler"
Exit
Go to C drive
Choose to Windows Folder
Click show content
Choose system32 folder
Choose spool folder
Choose printer
And delete all printing jobs pending
Again go back to CMD window and type the word "net start spooler"
Restart your computer also turn off your printer and switch it on.
It will work fine right now
I hope it helps you
