To get your printer back online, follow these steps:

1. **Check Basics:**
– Ensure the printer is **powered on** with no error lights blinking.
– Verify the printer is **properly connected** via USB, Ethernet, or Wi-Fi to the same network as your computer.
– If wireless, confirm it’s connected to your correct Wi-Fi network, not a guest or neighbor’s network[2].

2. **Restart Devices:**
– Turn off your printer; unplug it if needed.
– Restart your router or modem and wait about 30–60 seconds.
– Restart your computer.
– Turn the printer back on[1][2][4].

3. **Check Printer Status in Windows:**
– Open **Control Panel** or go to **Settings > Bluetooth & Devices > Printers & Scanners** (Windows 11).
– Select your printer, then open the **Print Queue**.
– In the **Printer** menu, make sure **“Use Printer Offline”** is *unchecked*. If it is checked, uncheck it to bring the printer online[2][3].
– Set your printer as the **Default Printer**, if not already set.
– If the printer still appears offline, try **removing and re-adding** the printer via the settings.

4. **For Mac (macOS Sonoma):**
– Go to **System Settings > Printers & Scanners**.
– Select your printer and click **“Resume”** in the print queue if available[2].

5. **Additional Tips:**
– Print a **Network Configuration Page** from your printer’s settings to verify its network status.
– Physically check cables for wired connections.
– If possible, update your printer driver/software to the latest version.

Following these steps usually resolves common offline printer issues and brings your printer back online[1][2][3][4].
