Prevención y mantenimiento

Assigning a static IP address to your printer in the router settings can prevent future connectivity drops. Keep your firmware current by using the printer's web interface or the HP Smart app to ensure the latest wireless drivers are installed. Using a stable 2.4GHz network is crucial for reliable performance.
