Printer Keeps Going Offline on Mac? Troubleshooting Guide

If your printer keeps going offline on Mac, the problem usually means your Mac is temporarily unable to communicate with the printer. The printer may be powered on and connected to Wi-Fi, yet macOS can still display an offline, unavailable, or not responding status.

Printer offline problems can happen because of an unstable wireless connection, incorrect printer configuration, a stuck print queue, outdated software, network changes, or temporary communication errors. Fortunately, many of these problems can be resolved with basic troubleshooting.

This guide explains why a printer is offline on Mac and provides step-by-step solutions to help get it back online.

Why Does My Printer Keep Going Offline on Mac?

A printer becomes available when your Mac can successfully communicate with it through Wi-Fi, Ethernet, USB, or another supported connection. If that communication is interrupted, macOS may show the printer as offline.

Common reasons include:

• Printer and Mac connected to different Wi-Fi networks

• Weak or unstable wireless connection

• Printer entering sleep mode

• Router connectivity problems

• Stuck or corrupted print jobs

• Incorrect printer configuration

• Outdated printer software

• USB or Ethernet cable problems

• Network address changes

• macOS updates affecting existing printer settings

• Temporary printing system errors

The right solution depends on whether the issue comes from the printer, Mac, or network.

1. Check Whether the Printer Is Turned On

Before changing any settings on your Mac, check the printer itself.

Make sure the printer is powered on and showing a ready status. Look for warning lights or messages related to paper jams, empty paper trays, low supplies, open covers, or other hardware conditions.

If the printer appears frozen, restart it.

Turn it off, disconnect the power cable, wait about 30 to 60 seconds, reconnect the cable, and turn the printer back on.

Once the printer finishes starting, check its status on your Mac again.

2. Check the Printer's Wi-Fi Connection

Wireless connectivity is one of the most common reasons a printer keeps going offline on Mac.

Open the printer's network or wireless settings and confirm that it is connected to your Wi-Fi network.

Next, verify the network being used by your Mac.

Your Mac and printer should normally be connected to the same local network. Problems can occur when the Mac is connected to the main Wi-Fi network while the printer is connected to a guest network, secondary router, or another wireless network.

If necessary, reconnect the printer to the correct Wi-Fi network.

3. Restart Your Mac, Printer, and Router

Temporary network problems can often be resolved by restarting the devices involved.

Turn off the printer and restart your Mac. If you are using a wireless printer, restart your router as well.

After the router becomes fully operational, turn the printer back on and wait until it reconnects to Wi-Fi.

Then check whether the printer appears online on your Mac.

This simple process refreshes network connections and can resolve temporary communication errors.

4. Check the Printer Queue on Mac

A stuck print job can prevent other documents from printing and may make the printer appear unavailable.

Open:

Apple menu > System Settings > Printers & Scanners

Select your printer and open its print queue.

Look for documents displaying errors, paused status, or unusually long processing times.

Delete or cancel failed print jobs and resume the printer if it has been paused.

After clearing the queue, try printing a small document or test page.

5. Make Sure the Printer Is Not Paused

Sometimes a printer appears offline because its print queue has been paused.

Open Printers & Scanners, select the printer, and view the print queue. If you see an option to resume printing, select it.

Wait a few moments and check whether pending documents begin printing.

If nothing happens, cancel the print jobs, restart the printer, and try again.

6. Remove and Add the Printer Again

If the printer is offline on Mac even though the network connection appears normal, removing and reinstalling the printer may help.

Go to:

Apple menu > System Settings > Printers & Scanners

Select the affected printer and use the available option to remove it.

Restart your Mac and printer.

Return to Printers & Scanners, choose Add Printer, Scanner, or Fax, and allow your Mac to search for available printers.

Select your printer and complete the setup process.

Re-adding the printer creates a fresh connection and may resolve incorrect or outdated printer configurations.

7. Check the USB Connection

If you use a USB printer instead of Wi-Fi, inspect the cable.

Disconnect the USB cable from both devices and reconnect it securely. If the printer remains offline, try another USB port if one is available.

You can also test another compatible cable.

USB hubs and adapters can sometimes create communication problems. When troubleshooting, connecting the printer directly to the Mac may help determine whether an adapter or hub is causing the issue.

8. Update macOS and Printer Software

Outdated software can contribute to printer communication problems.

Check your Mac for available system updates:

Apple menu > System Settings > General > Software Update

Install appropriate updates and restart your Mac if required.

You should also check whether updated printer software or drivers are available for your printer model.

When downloading printer software, use the official source associated with your device rather than unknown third-party download websites.

9. Check Whether the Printer's Network Address Changed

Wireless and Ethernet printers typically receive a network address from the router.

That address can sometimes change after the router or printer restarts. If your Mac is still attempting to communicate using an old configuration, the printer may appear offline.

Removing and adding the printer again can often resolve this because macOS searches for the printer using its current network information.

For recurring network-address problems, reviewing the printer and router network configuration may be necessary.

10. Reset the Printing System

If multiple printer settings appear corrupted or the previous troubleshooting methods have failed, resetting the Mac printing system may help.

However, this should generally be considered an advanced troubleshooting step because resetting the printing system can remove configured printers, print queues, and related settings.

After performing a reset, you may need to add your printer again and restore the required printing configuration.

Therefore, try basic connection, queue, restart, and reinstall steps before using this option.

11. Check Firewall and Network Security Settings

Firewall, VPN, security, or network-isolation settings can sometimes interfere with communication between a Mac and wireless printer.

If the printer started showing offline immediately after a network or security configuration change, review those settings.

If you use a VPN, you can temporarily disconnect it for troubleshooting and check whether local printer communication returns.

Avoid permanently disabling important security features. Instead, identify the setting preventing legitimate local network communication.

12. Move the Printer Closer to the Router

If your printer repeatedly switches between online and offline, weak Wi-Fi may be responsible.

Walls, floors, electronic equipment, and distance can reduce wireless signal quality.

Try moving the printer closer to the router or reducing obstacles between them.

If the printer works normally after being moved, wireless signal quality was likely contributing to the problem.

Printer Connected to Wi-Fi but Offline on Mac

Sometimes the printer reports a successful Wi-Fi connection while the Mac still considers it offline.

In this situation, verify that both devices are on the same network. Then clear the print queue, restart both devices, and remove and add the printer again.

Also check whether the router has recently been replaced or its network name, password, or configuration has changed.

A printer can appear connected while still being unavailable to a specific computer.

Printer Offline After macOS Update

If your printer went offline after a macOS update, an existing printer configuration or older software may no longer communicate correctly.

Restart both devices first and check for additional software updates.

If the printer remains offline, remove it from Printers & Scanners and add it again. Reinstall updated printer software if your setup requires additional drivers or utilities.

Avoid immediately assuming the printer is incompatible. A fresh setup may restore normal communication.

How to Prevent a Printer From Going Offline on Mac

Maintaining a stable connection can reduce repeated offline problems.

Keep your Mac and printer software updated, maintain a reliable Wi-Fi signal, avoid frequently changing network settings, and clear failed print jobs instead of leaving them in the queue.

If the printer frequently disconnects after long periods of inactivity, review its sleep, energy-saving, and network settings.

Regularly restarting network equipment can also help when recurring connectivity problems are affecting multiple devices.

Final Thoughts

When a printer keeps going offline on Mac, begin with simple troubleshooting. Check the printer's power and status, confirm the Wi-Fi or cable connection, clear the print queue, and restart the printer, Mac, and router.

If the problem continues, remove and add the printer again, install appropriate software updates, and check the network configuration. More advanced options, such as resetting the printing system, should generally be saved until basic troubleshooting has been exhausted.

By identifying whether the problem comes from the connection, print queue, software, or network, you can usually get an offline printer back online and reduce the chances of the issue returning.
