Introduction
What is printer firmware? If you’ve ever wondered why your printer occasionally prompts you to install updates, you’re not alone. Most people ignore these notifications, thinking they’re unnecessary or too technical to bother with.
Here’s the truth: printer firmware is the hidden software that makes your printer actually work. And yes, those updates? They’re more important than you might think. Outdated firmware can cause printing errors, security vulnerabilities, and even complete device failures.
In this guide, I’ll break down what is printer firmware in simple terms, explain why updates matter, and show you exactly how to keep your printer running smoothly. Whether you’re using an HP, Canon, Epson, or Brother printer, this information applies to you.
Let’s dive in and demystify printer firmware once and for all.
What Is Printer Firmware?
Think of printer firmware as your printer’s operating system—the built-in software that controls everything the printer does.
Unlike the driver software you install on your computer, firmware lives inside the printer itself. It’s stored on a chip inside the device and tells the printer how to interpret commands, manage print jobs, control paper feeding, and communicate with your computer or network.
Here’s a simple analogy: If your printer were a car, the firmware would be the engine control unit. It makes all the mechanical parts work together smoothly. Without it, your printer is just a plastic box with moving parts that don’t know what to do.
What firmware controls:
- Print quality and color calibration
- Paper handling and feeding mechanisms
- Network connectivity (Wi-Fi, Ethernet, USB)
- Security protocols and encryption
- Compatibility with different file types
- Error detection and reporting
- Power management features
Every time you send a document to print, the firmware interprets that data and translates it into physical movements—pulling paper, spraying ink, or applying toner in precise patterns.
The firmware also manages communication between your printer and computer. When you click “print,” your computer sends data that the firmware processes and executes.
Different from printer drivers: People often confuse firmware with drivers, but they’re different. Drivers are software on your computer that helps your operating system communicate with the printer. Firmware is software inside the printer itself that makes the hardware function.
You need both working properly for successful printing.
Why Printer Firmware Updates Actually Matter
Okay, so now you know what is printer firmware. But why should you care about updating it?
Manufacturers release firmware updates for several critical reasons, and ignoring them can lead to real problems.
Security vulnerabilities: This is the big one. Printers connected to networks can be entry points for hackers. Seriously. Cybersecurity experts have documented cases where hackers accessed company networks through outdated printer firmware.
Firmware updates patch these security holes. If you’re using your printer on a home or office network, keeping firmware current protects all your connected devices.
Bug fixes and stability: Just like any software, printer firmware can have bugs. These might cause random errors, paper jams, print quality issues, or connectivity problems. Updates fix these glitches and make your printer more reliable.
I’ve seen printers that constantly dropped Wi-Fi connections suddenly work perfectly after a firmware update. The problem wasn’t the network—it was outdated firmware.
New features: Sometimes manufacturers add new capabilities through firmware updates. This might include support for new paper sizes, improved mobile printing options, or enhanced color management.
You might get features you didn’t even know your printer could do—just by updating.
Improved performance: Updates can make printing faster, more accurate, and more efficient. Manufacturers continually optimize how firmware manages resources, and these improvements come through updates.
Compatibility: As operating systems evolve (new versions of Windows, macOS, or mobile platforms), your printer’s firmware needs updates to stay compatible. Without them, your printer might stop working with your computer after an OS update.
The reality check: Not every firmware update is critical. But skipping them entirely is risky. Security updates especially shouldn’t be ignored if your printer connects to the internet or a network.
How to Check If Your Printer Firmware Needs Updating
Before you can update printer firmware, you need to know what version you’re currently running and whether an update is available.
Method 1: Check on the printer itself
Many modern printers have built-in screens that display firmware information.
Navigate to your printer’s settings menu (usually under System, Settings, or Tools). Look for options like:
- “Firmware Version”
- “About This Printer”
- “System Information”
- “Device Information”
Write down the version number you see.
Method 2: Print a configuration page
Most printers can print a status or configuration page that includes firmware version information.
This option is usually found in the printer’s menu under “Reports,” “Information,” or “Print Configuration.” The exact location varies by manufacturer.
Method 3: Check from your computer
On Windows:
- Open Control Panel
- Go to Devices and Printers
- Right-click your printer
- Select “Printer Properties”
- Look for a “Firmware” or “About” tab
On Mac:
- Open System Settings (or System Preferences)
- Click on Printers & Scanners
- Select your printer
- Click “Options & Supplies”
- Look for firmware information under “General” tab
Method 4: Use the manufacturer’s software
Most printer manufacturers provide utility software that checks firmware versions and notifies you of available updates. These include:
- HP Smart App (for HP printers)
- Canon IJ Printer Utility
- Epson Software Updater
- Brother iPrint&Scan
These apps usually auto-detect when firmware updates are available.
Checking for available updates:
Once you know your current version, visit your printer manufacturer’s support website. Enter your printer model number and check the downloads or firmware section.
Compare the available firmware version with what’s currently installed. If the website version is newer, an update is available.
External resource for checking printer support: Visit your manufacturer’s support page directly through their official website (e.g., HP Support, Canon, Epson, or Brother support pages).
Step-by-Step Guide: How to Update Printer Firmware Safely
Updating firmware isn’t difficult, but you need to follow the process carefully to avoid problems.
Important precautions before you start:
- Read the update notes: Manufacturers explain what each update fixes. Make sure the update applies to your exact printer model.
- Don’t interrupt the process: Never turn off the printer or disconnect it during a firmware update. This can “brick” your printer—making it completely unusable.
- Ensure stable power: If possible, connect your printer to a UPS (uninterruptible power supply) or make sure your power won’t fail during the update.
- Back up settings: Some updates reset printer settings to defaults. Note your current configuration.
Method 1: Automatic update (easiest)
Many modern printers can update themselves automatically.
- Ensure your printer is connected to the internet (via Wi-Fi or Ethernet)
- Navigate to the printer’s settings menu
- Look for “Firmware Update,” “Web Services,” or “Software Update”
- Select “Check for Updates” or enable automatic updates
- If an update is available, select “Install” or “Update Now”
- Wait patiently while the update downloads and installs
- The printer will likely restart when finished
This is the safest method because the printer manages the entire process.
Method 2: Update via manufacturer’s software
Most manufacturers provide desktop software that handles updates.
- Download and install your printer manufacturer’s utility software
- Open the application and ensure your printer is detected
- Look for an update or maintenance section
- Click “Check for Updates”
- If firmware is available, follow the on-screen prompts
- Keep your computer and printer connected throughout
- Wait for the confirmation message
Method 3: Manual download and install
For older printers or specific situations, you might need to manually download firmware.
- Visit your printer manufacturer’s official support website
- Enter your exact printer model number
- Navigate to the “Downloads” or “Drivers & Software” section
- Find and download the latest firmware file
- Extract the file if it’s in a compressed format
- Connect your printer to your computer via USB (recommended for manual updates)
- Run the firmware installer you downloaded
- Follow the installation wizard instructions
- Do not use the printer or disconnect it until the process completes
What happens during the update:
Your printer might display progress bars, flash lights, make unusual noises, or restart multiple times. This is all normal. The update typically takes 5-15 minutes.
After the update:
- Verify the new firmware version installed correctly
- Print a test page to ensure everything works
- Reconfigure any settings that reset to defaults
- Test all functions you regularly use (scanning, copying, wireless printing)
Common Printer Firmware Update Mistakes to Avoid
Even though updating printer firmware is straightforward, people make mistakes that cause problems.
Mistake 1: Updating the wrong model’s firmware
This is surprisingly common. Downloading firmware for a similar but different printer model can damage your device.
Always double-check your exact model number. It’s usually on a label on the printer itself. Model numbers matter—HP OfficeJet Pro 8025 firmware won’t work on an 8035.
Mistake 2: Interrupting the update process
Never turn off your printer, disconnect cables, or close update software while firmware is installing.
If power fails during an update, your printer might become unresponsive. Some manufacturers provide recovery procedures, but it’s complicated and not always successful.
Mistake 3: Skipping the instructions
Each manufacturer has specific update procedures. Skipping steps or assuming all printers update the same way causes problems.
Read the release notes and instructions provided with the firmware download.
Mistake 4: Not checking compatibility
Some firmware updates have prerequisites—like needing a minimum current firmware version before installing the latest one.
Read the compatibility information carefully before downloading.
Mistake 5: Using Wi-Fi for manual updates
When manually installing firmware, always use a USB connection if possible. Wi-Fi can drop during the update, which causes failures.
Mistake 6: Ignoring post-update problems
If your printer doesn’t work correctly after updating, don’t just assume it’s broken. Sometimes you need to:
- Restart your computer and printer
- Reinstall printer drivers
- Reconfigure network settings
- Run the manufacturer’s troubleshooting utility
Mistake 7: Updating firmware to fix non-firmware issues
Firmware updates won’t fix hardware problems like mechanical failures, dried ink, or physical damage. If your printer has physical issues, firmware updates won’t help.
Troubleshooting Printer Firmware Update Problems
Sometimes firmware updates don’t go smoothly. Here’s how to handle common issues.
Problem: Update fails to install
- Check your internet connection (for automatic updates)
- Verify you downloaded the correct firmware for your exact model
- Temporarily disable antivirus software (it sometimes blocks firmware updates)
- Restart both your printer and computer, then try again
- Try a different update method (manual instead of automatic, or vice versa)
Problem: Printer won’t turn on after update
- Unplug the printer completely for 60 seconds
- Plug it back in and try powering on
- If it still doesn’t work, check the manufacturer’s website for recovery instructions
- Contact manufacturer support—they may have special procedures for failed updates
Problem: Features stopped working after update
- Print a configuration page and verify the firmware installed correctly
- Reinstall printer drivers on your computer
- Reset the printer to factory defaults (this won’t revert firmware, but may fix configuration issues)
- Check manufacturer forums to see if others reported similar issues
Problem: Update keeps failing at the same point
- Clear the printer’s memory by turning it off for several minutes
- Free up memory by canceling any stuck print jobs
- Disconnect all unnecessary cables except power and USB (if doing manual update)
- Try updating during a different time (off-peak hours can improve download speeds)
Problem: Can’t find firmware updates for your printer
- Verify you’re searching with the exact model number
- Check if your printer is too old—manufacturers eventually stop supporting legacy models
- Look for “End of Life” notices on the support page
- Consider that your printer might already have the latest firmware
When to contact support:
If you’ve tried everything and the update still won’t install, or your printer is unresponsive after a failed update, contact manufacturer support. Have your model number, serial number, and firmware version (if you know it) ready.

Frequently Asked Questions About Printer Firmware
Do I really need to update printer firmware regularly?
You should check for updates every 3-6 months, especially for network-connected printers. Security updates are critical if your printer has internet access. However, if your printer works perfectly and isn’t connected to networks, updates are less urgent. The biggest risk of not updating is security vulnerabilities.
Will updating firmware delete my printer settings?
Sometimes yes, sometimes no. Major firmware updates might reset certain settings to defaults, though most preserve your configuration. Before updating, note your current settings (network info, paper preferences, etc.) so you can reconfigure if needed. Your saved documents and files won’t be affected—firmware only controls the printer itself.
Can I roll back to old firmware if I don’t like the update?
This depends on the manufacturer. Some allow firmware downgrades, while others don’t. HP and Brother sometimes permit this, but it’s complicated and risky. Most manufacturers recommend against downgrading because newer firmware includes security fixes. Check your specific manufacturer’s policy before attempting any rollback.
What happens if power fails during a firmware update?
This is the worst-case scenario and can render your printer unusable—a situation called “bricking.” Some manufacturers have recovery modes or procedures to restore firmware after failed updates, but success isn’t guaranteed. This is why using a UPS or ensuring stable power during updates is crucial. If this happens, contact manufacturer support immediately.
How long should a printer firmware update take?
Most firmware updates complete in 5-15 minutes. Complex updates might take up to 30 minutes. If your update is taking longer than an hour without any progress indication, something is wrong. Don’t interrupt it immediately though—wait at least 90 minutes before contacting support. The printer might appear frozen but still be processing.
Conclusion
Understanding what is printer firmware and keeping it updated doesn’t have to be complicated or scary. It’s simply the software inside your printer that makes everything work properly.
The key takeaways: firmware updates improve security, fix bugs, add features, and keep your printer compatible with modern systems. Check for updates every few months, especially for networked printers. Follow the update process carefully, never interrupt it, and use the method recommended by your manufacturer.
Yes, most printers work fine without constant firmware attention. But when security vulnerabilities are discovered or critical bugs are fixed, those updates become genuinely important.
Now that you know what is printer firmware and how to manage it, you can keep your printer running smoothly and securely for years to come. Set a reminder to check for updates quarterly, and you’ll be ahead of most users.
Your printer is an important investment—treat its firmware like you treat your computer’s operating system updates. A few minutes of maintenance today prevents headaches tomorrow.
