Your computer can’t see where your printer is on the network, and your printer goes offline. This is typically caused by a DHCP IP address conflict — your router reassigns the printer the new IP address but your computer continues to try to communicate with the old IP address. The fix is to set your printer’s IP Address (in the router settings), to be permanent (static). This is explained completely in detail in Fix 3 below.
Your printer continually disconnects from the network. You restart it. It returns back on line. Three hours later, it is back offline. The computer is turned back on. Still offline. Unplug the printer and plug it in. Go online for one day, then offline. This cycle has been ongoing for weeks and you are still wondering, “Why?This cycle has been ongoing for weeks and you still don’t know why?
Printer offline is the most frequent printer issue in U.S. offices. It occurs on HP printers, Canon printers, Brother, Epson, (and basically any brand on any windows version). People never fix it permanently because they’re fixing the symptom of the problem (restart the printer) instead of the cause of the problem (the network cannot always locate the printer).
This guide will tell you exactly why your printer is offline and provide you with 7 fixes — from easy to permanent. For about 70% of offices using Fix 3, it fixes recurring offline errors.
Why Printers Go Offline — The Real Explanation
A printer going offline does not mean the printer is broken. It means the communication link between your computer and the printer has been lost. This communication happens over your network, and it depends on your computer knowing exactly where to find the printer.
Your printer’s location on the network is defined by its IP address — a number like 192.168.1.45. Your computer stores this address and uses it to send print jobs. The problem begins when your router assigns a different IP address to the printer — which happens regularly on most home and small office networks because routers use a system called DHCP to distribute IP addresses dynamically. When the printer gets a new address and the computer is still looking at the old one, the printer appears offline even though it is sitting in front of you, powered on and ready to print.
This is why restarting the printer or computer only works temporarily. The restart gives both devices a fresh start and they re-find each other — but the next time the router renews its IP assignments, the conflict happens again.
Fix 1: Full Restart Sequence
Before attempting any technical fix, perform a complete restart of all devices in the print chain. This resolves approximately 30% of offline errors caused by temporary communication glitches.
- Turn off the printer completely by pressing and holding the power button until the device shuts down. Do not use sleep mode.
- Unplug the printer’s power cable from both the printer and the wall outlet. Wait 60 full seconds.
- Unplug your WiFi router from power. Wait 30 seconds.
- Plug the router back in and wait for it to fully reconnect — watch for the internet light to stabilize, typically 60 to 90 seconds.
- Plug the printer back in and power it on. Wait 2 full minutes for the printer to fully initialize.
- On your computer, go to Settings > Bluetooth & Devices > Printers & Scanners. Check whether the printer now shows as Ready.
- Send a test print.
If the printer comes online and stays online for more than a day before going offline again, the IP address conflict is the cause. Apply Fix 3 immediately to prevent recurrence.
Fix 2: Uncheck 'Use Printer Offline' in Windows
Windows has a manual setting called Use Printer Offline that, when enabled, puts the printer into offline mode regardless of its actual network status. Windows updates sometimes enable this setting silently. This check takes under 60 seconds.
- Go to Start > Settings > Bluetooth & Devices > Printers & Scanners.
- Select your printer from the list and click Open print queue.
- In the print queue window, click Printer in the top menu bar.
- Look for a checkmark next to Use Printer Offline. If it is checked, click it to uncheck it.
- Close the print queue window and try printing a test page.
If the Use Printer Offline option is not checked and the printer is still offline, proceed to Fix 3.
Fix 3: Assign a Static IP Address — The Permanent Fix
This is the most important fix in this guide. A static IP address means your router always gives the printer the same network address — no more IP conflicts, no more offline errors caused by address changes. Once applied, this fix is permanent and requires no ongoing maintenance.
You need two things before starting: your printer’s MAC address (a unique hardware identifier printed on a label on the bottom or back of the printer, formatted like 00:1A:2B:3C:4D:5E) and access to your router’s admin panel.
Step 1 — Find Your Printer's MAC Address
For most printers, print a Network Configuration Page or Network Status Sheet from the printer’s control panel. Go to Settings or Information > Network > Print Network Status Sheet. The MAC address is listed on this page alongside the current IP address.
Step 2 — Access Your Router Admin Panel
Open a web browser on any device connected to your network. Type your router’s default IP address in the address bar. The most common router admin addresses are 192.168.1.1, 192.168.0.1, and 10.0.0.1. If none of these work, check the label on your router — the admin address is usually printed there. Log in with your router admin credentials.
Step 3 — Find DHCP Reservation or Static IP Setting
Every router brand uses slightly different terminology. Look for one of these in your router menu: DHCP Reservation, Static IP Allocation, IP-MAC Binding, or Address Reservation. It is typically found under Advanced Settings, LAN Settings, or Connected Devices depending on your router brand.
Step 4 — Add the Printer Reservation
Add a new reservation entry. Enter your printer’s MAC address exactly as it appears on the configuration page. Assign it a fixed IP address — choose an address in your network’s range that is outside your router’s normal DHCP pool to avoid future conflicts. For example, if your network uses addresses in the 192.168.1.1 to 192.168.1.254 range and your router assigns DHCP addresses up to 192.168.1.150, assign the printer 192.168.1.200.
Step 5 — Restart and Verify
Save the reservation setting. Restart your router and printer. After both fully restart, print a new Network Configuration Page and confirm the printer now shows the static IP address you assigned. Go to Settings > Printers & Scanners on your computer, remove and re-add the printer, and confirm it connects at the new static IP.

Fix 4: Restart the Windows Print Spooler Service
The Print Spooler is the Windows service that manages all print jobs and printer communication. When the spooler crashes or freezes, printers show as offline even if the network connection is fine. Restarting it takes 3 minutes.
- Press Windows + R on your keyboard. Type services.msc and press Enter.
- In the Services window, scroll down to Print Spooler.
- Right-click Print Spooler and click Stop. Wait 15 seconds.
- Open File Explorer. Navigate to: C:\Windows\System32\spool\PRINTERS
- Delete all files inside this folder. Do not delete the PRINTERS folder itself — only the files inside it.
- Go back to Services. Right-click Print Spooler and click Start.
- Try printing a test page.
Deleting the files in the PRINTERS folder clears any corrupted print jobs that can cause the spooler to crash again immediately after being restarted. This step is critical — many guides tell you to restart the spooler without clearing the folder, which is why the problem returns.
Fix 5: Reinstall or Update Printer Drivers
An outdated or corrupted driver causes Windows to lose reliable communication with the printer, which often manifests as an offline status. Driver issues spike after major Windows updates, which sometimes replace manufacturer drivers with generic Microsoft drivers.
- Go to Settings > Bluetooth & Devices > Printers & Scanners.
- Select your printer and click Remove device. Confirm the removal.
- Go to the printer manufacturer’s official support website for your brand: support.hp.com (HP), usa.canon.com/support (Canon), support.brother.com (Brother), epson.com/support (Epson).
- Search for your exact model number. Download the full driver and software package for your version of Windows (Windows 10 or Windows 11, 64-bit).
- Run the installer with the printer turned on and connected. Follow all installation steps.
- Restart your computer after the driver installation completes.
- Test with a print job.
Always download printer drivers directly from the manufacturer’s official website. Third-party driver download sites frequently contain outdated files, adware, or malware.
Fix 6: Remove and Re-Add the Printer
Sometimes Windows’s stored printer configuration becomes corrupted or references an outdated IP address or port. Removing the printer completely and adding it fresh forces Windows to create a clean connection.
- Go to Settings > Bluetooth & Devices > Printers & Scanners.
- Select your printer and click Remove device.
- Click Add device. Windows will scan for printers on your network.
- If your printer appears in the scan results, select it and click Add device.
- If it does not appear, click The printer I want isn’t listed, then choose Add a printer using a TCP/IP address or hostname. Enter the printer’s static IP address (from Fix 3) and follow the prompts.
- Install the manufacturer’s full driver package after adding the printer.
Fix 7: Check Firewall and Security Software
Security software updates sometimes add new firewall rules that block printer communication ports. This is especially common with third-party antivirus programs on Windows 11.
- Temporarily disable your antivirus or Windows Defender Firewall.
- Try printing. If the printer comes online with the firewall disabled, the security software is blocking it.
- Re-enable your security software. Open its settings and add an exception or allow rule for your printer’s IP address.
- The specific ports used for printing are: TCP port 9100 (RAW printing), TCP port 631 (IPP), and UDP port 5353 (mDNS/Bonjour for device discovery). Add exceptions for these ports in your firewall if adding the IP address alone does not resolve it.
For businesses on a domain network with centrally managed firewall policies, contact your IT administrator or Ovron Inc to add the appropriate printer exceptions at the network level.
Brand-Specific Notes
HP Printers
HP OfficeJet and LaserJet printers on wireless networks are the most commonly reported brand for recurring offline errors. The HP Print and Scan Doctor tool (free from support.hp.com) is the best first-line diagnostic for HP-specific offline issues — it identifies the exact cause in most cases before you start manual fixes. For HP LaserJet models, the Embedded Web Server (accessed by typing the printer’s IP in a browser) provides detailed connectivity diagnostics.
Canon Printers
Canon printers sometimes switch to offline mode after the Canon IJ Network Device Setup Utility loses its registration. Reinstalling the Canon full software package from usa.canon.com/support and re-running the network tool reregisters the printer on the network and resolves offline errors that do not respond to the other fixes
Brother Printers
Brother printers default to a network configuration that makes them particularly susceptible to IP conflicts. After applying Fix 3 (static IP), verify the printer’s port in Windows Printer Properties is configured to use the TCP/IP port matching the static IP — not a WSD (Windows Standard Driver) port, which updates automatically but less reliably.
Epson Printers
Epson EcoTank and WorkForce models on 5GHz WiFi networks frequently drop connection because many Epson models only support 2.4GHz. If your printer connects to a dual-band router, ensure the printer is connected to the 2.4GHz network specifically, not the 5GHz band or a combined network name that switches automatically between bands.
When to Call a Printer Support Professional
Contact a printer support company when any of the following are true after applying all relevant fixes above.
- The printer goes offline more than once per week despite having assigned a static IP
- Multiple printers in the same office experience offline errors simultaneously — indicating a network-level problem
- The printer shows online in Settings but print jobs still do not complete — indicating a deeper driver or port configuration issue
- The offline error began immediately after a network infrastructure change (new router, new ISP, office relocation)
- Your office has 5 or more printers and managing individual IP assignments is not feasible without centralized tools
Frequently Asked Questions
The WiFi connection and the IP address are separate issues. Your printer can be connected to WiFi but still appear offline if the IP address has changed since your computer last connected to it. Run a full restart sequence first. If the problem recurs, assign a static IP via your router — this is the permanent solution for WiFi-connected printers.

This indicates the printer port in Windows is not pointing to a consistent address. Either the printer’s IP is changing after restarts (fix with static IP assignment) or the printer port is configured to a WSD address that Windows is having trouble resolving. Remove and re-add the printer using its static IP address and a TCP/IP port rather than WSD
Yes — all 7 fixes in this guide are designed for non-technical users. Fixes 1, 2, 4, and 5 require no router access. Fix 3 requires access to your router’s admin panel but is step-by-step with no specialist knowledge needed. Fixes 6 and 7 are standard Windows settings. If all 7 fixes fail to resolve the issue permanently, the root cause is likely a network configuration problem that benefits from professional diagnosis.
The most common trigger for sudden offline errors in a printer that previously worked well is a router firmware update that resets DHCP settings, clearing any static IP reservations you had set. Check your router’s DHCP reservation list — if it is empty, your printer’s static IP assignment was lost and must be re-entered.
