<human>:  How can I troubleshoot the printer that won't work?
<bot>: The first step in troubleshooting a printer that won't work is to make sure that you have a proper connection to the printer. Check that the power cord is connected securely, the USB cable is securely connected to both the printer and the computer or network, and that the printer is turned on. Another step is to check the printer's settings. Make sure that the paper size and type are set correctly, the paper tray is loaded with the correct paper, and the ink or toner cartridge is correctly installed. If your print job still won't print, you may need to reinstall the printing software.
