Seeing your wireless printer offline right before an important print job is one of those small tech problems that can ruin your morning. I have dealt with this myself across three different printers and two operating systems, and the good news is that most offline issues are easy to fix without calling support.
When a printer shows offline, it usually means your computer cannot communicate with it over your Wi-Fi network. The printer might be on and connected to the same router, but something in the chain is blocking the connection. In this guide, I will explain why your wireless printer keeps going offline and walk you through the exact steps I use to get it back online.
By the end, you will know how to fix the problem on both Windows and macOS, plus a few permanent adjustments that stop the issue from coming back.
Common Reasons Your Wireless Printer Shows Offline
Before you start clicking through settings, it helps to understand what is actually happening. Most wireless printer offline problems fall into one of six categories.
Your printer is no longer on the same Wi-Fi network
This is the most common cause. If your router reboots, if you changed the Wi-Fi password, or if the printer connected to a guest network instead of the main network, your computer will not find it. I have fixed this dozens of times by simply reconnecting the printer to the correct network.
The printer entered power saving or sleep mode
Many printers go into deep sleep to save power. Sometimes the wireless radio turns off with sleep mode and does not wake up properly when you send a job. This is one of the most underreported causes, and it is rarely covered in manufacturer guides.
Your router assigned a new IP address
Printers get an IP address from the router. If the router reboots or the lease expires, the printer may receive a different IP address than the one your computer remembers. This mismatch makes the printer look offline even though it is still connected to Wi-Fi.
The print queue or spooler is stuck
On Windows, the Print Spooler service manages every print job. If one job gets stuck, it can block everything after it and report the printer as offline. I have seen this happen after a failed PDF print or after the computer wakes from sleep.
Drivers are outdated, corrupted, or mismatched
A bad driver update or an old driver after a Windows or macOS upgrade can break communication with the printer. This often shows up as an offline status even when the network connection is fine.
Firewall or antivirus software is blocking the connection
Security software can sometimes block the ports your printer uses to talk to the computer. This is more common on office networks, but I have seen it on home setups after installing a new antivirus suite.
Quick Fix: Power Cycle Everything First
If you want the fastest fix, start here. Power cycling clears temporary network glitches and refreshes the connection between your devices.
- Turn off your printer and unplug it from the power outlet.
- Unplug your Wi-Fi router and modem from power.
- Shut down your computer fully, not just sleep or hibernate.
- Wait at least 60 seconds.
- Plug the modem and router back in and wait until all lights are stable.
- Plug the printer back in and turn it on.
- Turn your computer back on.
- Try printing a test page.
This simple restart sequence fixes about half of all wireless printer offline issues. If it does not work, move on to the deeper steps below.
How to Get Your Wireless Printer Back Online: Step-by-Step
These steps work on Windows 10, Windows 11, and macOS. I recommend doing them in order because each one rules out a different cause.
Step 1: Verify your printer is connected to the right Wi-Fi network
Use the printer’s built-in display or print a network configuration page. Look for the network name and signal strength. Make sure it matches the network your computer is using. If it does not, reconnect the printer through its wireless setup menu.
Step 2: Set your printer as the default printer
Windows sometimes sends jobs to a different printer, which makes your main printer look idle or offline.
On Windows 10 and 11:
- Open Settings and go to Bluetooth & devices > Printers & scanners.
- Find your printer and click it.
- Click Set as default.
On macOS:
- Open System Settings and click Printers & Scanners.
- Select your printer from the list.
- Click the Default Printer dropdown and choose your printer.
Step 3: Clear the stuck print queue
A stuck job can block new prints and trigger an offline message.
On Windows:
- Go to Settings > Bluetooth & devices > Printers & scanners.
- Click your printer and choose Open print queue.
- Select all documents and click Cancel.
On macOS:
- Open System Settings > Printers & Scanners.
- Click your printer, then click Open Print Queue.
- Select each stuck job and click the X to remove it.
Step 4: Reset the Print Spooler service on Windows
The Print Spooler is the Windows service that queues print jobs. Resetting it fixes many offline errors.
- Press Windows key + R, type services.msc, and press Enter.
- Scroll down and find Print Spooler.
- Right-click it and choose Restart.
- If Restart is grayed out, choose Stop, wait 10 seconds, then choose Start.
After the service restarts, try printing again. I have used this fix specifically when an HP Color LaserJet Pro MFP M479fdw kept going offline repeatedly after a few hours, which matches what many users report in technical forums.
Step 5: Update or reinstall your printer drivers
Old drivers are a silent cause of offline problems, especially after a major OS update.
On Windows:
- Go to Settings > Bluetooth & devices > Printers & scanners.
- Click your printer, then click Remove.
- Restart your computer.
- Download the latest driver directly from the printer manufacturer’s website.
- Install the driver and add the printer again.
On macOS:
- Open System Settings > Printers & Scanners.
- Click the minus button to remove the printer.
- Restart your Mac.
- Click the plus button and add the printer again. macOS usually downloads the correct driver automatically.
Step 6: Remove and re-add the printer
If your computer still sees the printer as offline, removing the device and adding it fresh forces a new connection handshake.
On Windows, go to Printers & scanners, click your printer, choose Remove, then restart. On macOS, remove the printer in Printers & Scanners and add it back with the plus button. After re-adding, print a test page before doing anything else.
Step 7: Restart your computer
It sounds basic, but restarting clears network caches, refreshes services, and resolves conflicts between background apps. If your printer went offline after your computer woke from sleep, this step alone often fixes it.
macOS-Specific Steps to Fix an Offline Printer
Mac users have a few extra tools that Windows does not offer. These have saved me when standard steps failed.
Reset the printing system
This clears every printer, driver, and job on your Mac.
- Open System Settings > Printers & Scanners.
- Right-click or Control-click anywhere in the printer list.
- Choose Reset printing system.
- Enter your administrator password when prompted.
- After the reset, add your printer again with the plus button.
Check for AirPrint conflicts
If your printer supports AirPrint but you also installed a manufacturer driver, macOS may switch between them and cause confusion. Try removing the printer and adding it using AirPrint only, or vice versa, depending on which works better for your model.
Permanent Fixes: Prevent Your Printer from Going Offline Again
If your printer keeps going offline after you fix it, the problem is usually at the network level. These adjustments address the root cause.
Assign a static IP address to your printer
The most reliable long-term fix is to reserve an IP address for your printer in your router settings. This prevents the router from giving the printer a new address after a reboot.
- Print a network configuration page from your printer to get its MAC address.
- Log into your router’s admin panel.
- Find the DHCP reservation or address reservation section.
- Enter the printer’s MAC address and assign a fixed IP address outside the dynamic range.
- Save and restart the printer.
This is the fix many technical community users recommend when a printer goes offline after router changes, and it has worked for me on both Brother and HP printers.
Disable deep sleep or power saving mode
On your printer’s display, look for Energy Settings, Power Save, or Sleep Mode. Set the sleep timer longer or disable deep sleep entirely. This keeps the wireless radio active so the printer responds faster to print jobs.
Update your router firmware
Router firmware updates sometimes change how devices connect. If your printer went offline right after a router update, check the manufacturer’s website for newer firmware or rollback instructions.
Clear DNS and network caches
On Windows, open Command Prompt as administrator and run ipconfig /flushdns. Then restart the Print Spooler. On macOS, run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder in Terminal. This clears stale network information that can confuse printer discovery.
Check firewall and antivirus settings
Temporarily disable your firewall or antivirus and try printing. If the printer comes online, add an exception for your printer’s IP address or the printer software. Remember to turn protection back on afterward.
