To get your printer back online, follow these effective troubleshooting steps:

1. **Check the Basics**
– Ensure the printer is powered on with no blinking error lights.
– Confirm all cables (USB, Ethernet) are securely connected if using a wired setup.
– Check that the printer is connected to the correct Wi-Fi network (not a guest or neighbor’s network). You can print a Network Configuration Page on most modern printers for detailed connection info[1][3].

2. **Power Cycle Devices**
– Turn off the printer and unplug it for about a minute, then plug it back in and turn it on.
– Restart your computer.
– Restart your router/modem and wait 30–60 seconds before turning the printer back on[1][3][5].

3. **Adjust Printer Settings on Your Computer**
– On **Windows 11**:
– Go to *Settings > Bluetooth & Devices > Printers & Scanners*.
– Select your printer and open the print queue.
– Click on the *Printer* menu and **uncheck “Use Printer Offline.”**
– Ensure the printer is set as the default if needed.
– If problems persist, try removing and re-adding the printer[1][2].
– On **macOS Sonoma**:
– Go to *System Settings > Printers & Scanners*.
– Select your printer, open the print queue, and click **“Resume”**[1].

4. **Network Troubleshooting for Wireless Printers**
– Verify your printer and computer are on the same Wi-Fi network.
– Check that your firewall or router settings are not blocking printer communication[3].

These steps cover the most common causes of printers appearing offline due to network, cable, power, or driver issues and should restore your printer to an online status[1][2][3][5].
