Key Takeaways
- A firmware update is the printer’s built-in software, and updating it can fix bugs, add features, and improve security.
- Only download firmware from your printer maker’s official support page, using your exact model number.
- Never turn off or unplug the printer while an update is running, or you risk permanently damaging it.
- Use a wired connection when you can, keep the printer plugged into stable power, and back up your settings first.
- If your printer works fine and no update is offered, you do not have to chase every release.
Firmware updates make a lot of people nervous, and honestly, that caution is healthy. A bad update can turn a working printer into an expensive paperweight. But the flip side is that outdated firmware causes maddening problems: dropped Wi-Fi, jobs stuck in the queue, and security holes. I have updated firmware on dozens of home and office printers, and the process is safe when you slow down and follow a few rules. By the end of this guide, you will know when an update is worth doing, how to get the right file, and exactly how to run it without bricking your machine.
What Printer Firmware Actually Is
Firmware is the small program that lives inside your printer and tells the hardware how to behave. It controls how the printer talks to your network, reads a print job, moves paper, and reports errors. Think of it as the printer’s own tiny operating system, separate from the driver that lives on your computer.
When a manufacturer releases new firmware, they are usually fixing something. That might be a connection bug, a paper-handling glitch, or a newly discovered security weakness. Occasionally an update also adds a feature, like support for a new mobile app or a cloud printing service.
Firmware is different from the printer driver on your PC or Mac. The driver is software you install to send documents to the printer. Firmware lives on the printer itself. You can update one without touching the other, though it is smart to keep both current. If you want the bigger picture on upkeep, our Complete Guide to Printer Maintenance ties all of these tasks together.
Should You Update Printer Firmware at All?
Here is the honest answer: not every update is urgent. The old workshop saying “if it isn’t broken, don’t fix it” has some truth for printers. If your machine prints reliably, connects without trouble, and no update is being pushed to you, there is no need to hunt one down.
That said, there are clear cases where you should update. If your printer keeps dropping off Wi-Fi, throws odd error codes, or your maker has published a security notice, an update to the firmware is often the real fix. Security updates matter more than most people think, because a networked printer is a door into your home or office network.
Good Reasons to Update
- You are seeing connection drops, spooler errors, or repeated jams that started recently.
- Your manufacturer released a security patch for your model.
- A feature you need, like a mobile printing app, requires newer firmware.
- Support told you to update while troubleshooting a real problem.
When to Wait
- The printer works fine and nothing is prompting you.
- The update is brand new and you have read reports of problems.
- You are in the middle of a big print run with a deadline.
Warning: The single most dangerous moment is mid-update. If power is cut while firmware is writing, the printer can be left in a broken state that a home user cannot easily recover. Never unplug, never switch off, and never yank the network cable until the printer clearly says the update is done and it has fully restarted.
Where to Get Firmware Safely
This is the part people get wrong most often. Firmware should only ever come from one place: your printer maker’s official support website. Search for your exact model number, which you can find on a sticker on the back or inside the machine, or printed on a configuration page from the printer’s menu.
Avoid random download sites, forum attachments, and “driver updater” tools that promise to scan your PC. These are a common source of malware, and a fake firmware file can genuinely destroy a printer. The major brands, including HP, Canon, Epson, and Brother, all host firmware on their own support pages, and they list it by model.
Many modern printers can also update themselves. In the settings menu you will often find a “Web Services,” “Preferences,” or “Maintenance” section with a “Firmware Update” or “Check for Updates” option. This built-in updater pulls directly from the manufacturer, so it is one of the safest routes. If you are unsure whether a source can be trusted, our page on how we research and test our advice explains the standards we hold ourselves to as well.
| Update method | Best for | What to watch out for |
|---|---|---|
| Printer’s built-in updater (on-screen menu) | Most home and small-office users | Needs a stable internet connection on the printer |
| Manufacturer’s desktop app or utility | People who already use the maker’s software | Only install the app from the official site |
| Manual file download from support page | Older or offline printers | Match the exact model and read instructions fully |
| USB flash-drive update | Printers with no network access | Format the drive as directed; do not remove it early |
| Choose the method that matches how your printer connects and how comfortable you feel. | ||
Before You Start: A Short Prep Checklist
A few minutes of prep prevents almost every firmware disaster. Do not skip these, even if the update looks quick.
- Confirm your exact model number so you download the right file.
- Plug the printer into a reliable outlet, ideally on a surge protector, not a flaky power strip.
- Use a wired USB or Ethernet connection if you can, since Wi-Fi can drop mid-update.
- Note down your current network settings and any custom preferences, in case they reset.
- Make sure no one else is about to send a print job.
Keeping your printer healthy overall makes updates smoother too. A machine that is already struggling with dust or clogged parts is more likely to hiccup. Our guide on how to clean your printer inside and out pairs well with this one, and if you are new to all of this, why printer maintenance matters is a friendly starting point.
How to Update Printer Firmware Step by Step
These steps work for most modern printers using the built-in updater. If you are updating manually from a downloaded file, the maker’s instructions replace steps 3 through 5, but the safety rules stay the same.
- Turn on the printer and let it fully wake up. Expected result: the display shows the home screen and the printer is ready, not mid-job or in an error state.
- Connect the printer to power and, ideally, to your network by cable. Expected result: a stable connection icon, or a lit Ethernet port, with no low-battery or sleep warnings.
- Open the settings menu and find the update option, often under Maintenance, Preferences, or Web Services. Expected result: a menu item like “Firmware Update” or “Check for Updates.”
- Select Check for Updates and wait. Expected result: the printer either reports it is up to date, or it finds a newer version and asks you to confirm.
- Confirm the update and leave the printer completely alone. Expected result: a progress bar or percentage, followed by an automatic restart. Do not touch anything.
- Print a test page once the printer restarts. Expected result: a clean page, and the updated firmware version shown in the printer’s info or status menu.
Tip: When I updated an aging home laser printer that kept dropping its wireless link, the whole firmware update took under six minutes over Ethernet, and the restart alone ate about ninety seconds of that. I set a phone timer for ten minutes and simply walked away, which removed any temptation to poke at it. The Wi-Fi problem disappeared after the update.
What to Do If Something Goes Wrong
First, do not panic and do not immediately unplug. If the update seems frozen, give it a generous amount of time, because some models pause for several minutes while writing. A stalled progress bar is not always a stalled update.
If the printer is clearly stuck for well over the time the maker lists, look for a recovery mode in the manufacturer’s support documents. Many brands have a specific button combination that boots the printer into a repair state so you can reload firmware. This is the moment to contact official support rather than guess.
After a successful update, you may find some settings have reset, such as paper size defaults or network names. Re-enter them from the notes you took. If print quality looks off afterward, run a nozzle check or cleaning cycle, and see our tips on habits that extend your printer’s life to keep things running well long term.

Frequently Asked Questions
How often should I update printer firmware?
There is no fixed schedule. Check for updates a few times a year, and always when you hit connection or security problems. If your printer offers automatic updates and works reliably, letting it manage itself is fine. Chasing every single release is unnecessary and adds needless risk.
Can a firmware update really damage my printer?
Yes, but almost always only if it is interrupted or if you install the wrong file. Cutting power mid-update or using firmware from an unofficial source are the real dangers. Use official downloads, keep the printer powered and connected, and leave it alone until it finishes, and the risk is very low.
Will updating firmware delete my saved settings?
Sometimes. Many updates keep your settings, but some reset network names, paper defaults, or scan-to-folder shortcuts. That is why it helps to write down your key settings first. If anything resets, you can simply re-enter it from your notes once the printer has restarted.
Is the firmware the same as the printer driver?
No. The driver is software on your computer that sends documents to the printer. Firmware is the program inside the printer that runs the hardware. You update them separately, though keeping both current gives you the fewest headaches. A firmware update happens on the printer, not on your PC.
Should I update firmware over Wi-Fi or a cable?
A cable is safer whenever it is an option. Wi-Fi can drop unexpectedly, and a lost connection during an update is exactly what you want to avoid. Ethernet or USB gives you a steady link. If Wi-Fi is your only choice, stay close to the router and keep the signal strong.
The Bottom Line
Updating printer firmware is not something to fear, but it does reward a little patience. Get the file from the official source, keep the power and connection stable, and never interrupt it once it starts. Do that, and an update becomes a quiet, ten-minute task that can quietly fix problems you have been living with for months.
If this helped, take a slow look at the rest of your maintenance routine. A little regular care, alongside the occasional firmware check, is what keeps a printer dependable for years. Whenever you are ready, browse our other maintenance guides and pick the next small task that fits your machine.
