To install the **HP LaserJet Pro M404dn printer driver**, follow these steps:
1. **Download the driver:**
– Visit the official HP website or a trusted source to download the latest HP LaserJet Pro M404dn driver compatible with your operating system (Windows, macOS, or Linux)[1][4].
2. **For Windows 11 (example):**
– After downloading the driver, extract the files if they come in a compressed format.
– Connect the printer to your PC via USB.
– Run the installer or manually add the printer driver through Windows Settings > Printers & scanners > Add a printer or scanner.
– If the installer does not auto-detect the printer, select the manual installation option and point it to the extracted driver files.
– Follow on-screen instructions to complete the installation[1].
3. **Testing:**
– Once installed, print a test page to verify the printer is working correctly with your PC[1].
4. **For macOS users:**
– The HP LaserJet Pro M404dn supports AirPrint, allowing driverless printing if both the Mac and printer are on the same network.
– If AirPrint does not work or issues arise, download the HP driver package for macOS from the HP website or Apple Support.
– Add the printer manually via System Preferences > Printers & Scanners, then select the downloaded driver or use the generic Postscript printer driver if necessary[2].
**Additional notes:**
– If connecting via USB on Windows 11, ensure the printer is turned on *before* booting the PC to avoid detection issues[3].
– Regularly update the printer firmware and drivers from HP’s official support page for optimal performance[3][4].
