Nam bought a new router, but now he can't print. Leo says it's a good idea to delete the connection in his printer, then go into the printer settings of his computer and delete the connection there. Then reinstall. It could be it just needs to be reacquired by the OS.
Ann tries to print something and it seems to be dead. It won't send the file to the printer. She gets an error message that Leo says is a trackpad error. But there's another error that says printer off line. Leo says that means it still thinks it's jammed. And windows has stopped the device because of continual problems. Leo says that could point to the trackpad failure. It's definitely a hardware issue. But Leo advises uninstalling the printer and then reboot the computer. Then try reinstalling it. See if that frees it up to print.
