If your printer isn't turning off or responding after a print job, it could be a result of the printer's power setting or simply because the print job is stuck in the queue. To resolve this issue, you should take the following steps:

1. Check the printer's power settings. See if the printer is set to enter a power-saving mode shortly after a print job. Make sure that this feature is disabled.
2. Check the printer queue. Go to the printer queue in the Settings menu of your computer and look for the stuck print job. Remove the stuck job and try printing again.
3. Restart your computer. In some cases, restarting your computer can remove any stuck print jobs from the queue.
4. Check the Wifi. Make sure that the printer is still connected to the same Wifi network as the computer.
