The “printer cannot be contacted over the network” error usually means your computer is unable to communicate with the printer via your local network due to connection or configuration problems. Common causes include unstable or incorrect network connections, IP address conflicts (especially if the printer uses a dynamic IP), disabled essential services, firewall or antivirus blocking, or outdated printer drivers.

To resolve this issue, you can try the following steps:

– **Check Physical and Wireless Connections:** Ensure Ethernet cables are securely connected or the Wi-Fi connection is stable on both the printer and router. Restart both the printer and router to reset connections[1][3][5].

– **Set a Static IP Address for the Printer:** Assigning a fixed IP address to your printer avoids issues caused by changing dynamic IPs. You can usually do this by accessing the printer’s network settings through its IP address in a web browser, then selecting manual IP configuration[2][4].

– **Verify and Enable Required Windows Services:** Network printing relies on specific Windows services. Confirm these services are running and set to automatic startup, especially after Windows updates[2].

– **Check Firewall and Antivirus Settings:** Temporarily disable or configure them to ensure they are not blocking printer communication or related services[5].

– **Update or Reinstall Printer Drivers:** Uninstall current drivers via Device Manager, then download and install the latest drivers from the printer manufacturer’s website to ensure compatibility and functionality[5].

– **Use Network Diagnostic Tools:** Many manufacturers provide diagnostic utilities to detect and fix connection issues automatically[3].

If these steps do not resolve the problem, contacting technical support is advisable as there could be deeper hardware or network issues involved[1].
