A modern company is increasingly like a fortress. Firewalls at the perimeter, antivirus on every laptop, two-factor authentication at every access, and encrypted backups in the cloud. We have strengthened the main door until it is almost impregnable, and we have invested substantial resources in raising awareness among employees to protect the data, the business’s most valuable asset.
And, meanwhile, in a corner of the office there remains a service door wide open: the printer. Connected to the same network as everything else, handling daily the most sensitive documents of the business and watched by almost no one.
The industry itself recognizes this plainly. Printers are no longer simple devices: they are connected endpoints and, therefore, real targets for any kind of attack. The good news is that this service door can be fortified as much as the main door. The bad news is that few organizations have done so yet.
Why the printer is a real target
It’s worth pausing to consider what flows through an office printer over the course of a workday: payrolls, contracts, financial reports, legal documents. All of that travels over the network, is processed on the device, and, at times, remains stored in its memory or waiting in the out tray.
A attacker who compromises that device won’t just access those documents. It becomes an entry point into the corporate network from a device that almost never appears in security inventories. It’s the unguarded flank—the one nobody watches until it fails.
And there’s another detail that tends to be overlooked: many office printers include internal storage where copies of what is printed, scanned, or faxed remain. In a framework like GDPR, a leak through an unattended printing device isn’t just a technical incident; it’s a compliance problem with legal and reputational consequences. The printer handles sensitive data, but it’s rarely treated as such.
Security starts in the BIOS, not in the antivirus
Here’s the shift in focus. Cybersecurity tends to concentrate on software, but a determined attacker aims lower. That’s why the core idea is clear: security doesn’t start with software; it starts with the BIOS.
HP’s Enterprise printers rely on HP Wolf Security, a protection layer built into the hardware itself. The first link is HP Sure Start: if an attacker tries to corrupt the device’s BIOS, the system automatically restores it to a secure master copy, with no human intervention required.
From there, two more defenses come into play. Whitelisting ensures the printer only runs firmware known and signed by HP, so malicious code is blocked instantly. And intrusion detection watches the device’s behavior in real time: at the first sign of an anomaly, it alerts IT before data can be compromised.
The best example is a compromised firmware update. Instead of installing it, the printer blocks it, self-recovers, and alerts IT, all without interrupting a single business process. The defense stops being the alarm that rings after the fact and becomes an automatic reflex.
HP aligns this automatic recovery with the NIST SP 800-193 guidelines on device cyber-resilience, the standard that defines how a device should detect an attack, protect itself, and autonomously return to a trusted state. Detect, stop, and recover: the three phases that separate a manageable scare from a serious problem.
A line designed with security first
That philosophy comes to life in HP’s new professional A4 lineup, which brings together two families: the LaserJet Pro 4000/4100 series, aimed at small to midsize businesses, and the LaserJet Enterprise 5000/6000 series, for higher-volume environments. Rather than get lost in endless feature lists, the company boils it down to three attributes to keep in mind: security, productivity, and reliability.
In security, these devices are designed from the ground up to protect firmware, data, and the network. The goal is to make the printer stop being the weak link in the chain and become a secure asset within the IT environment. HP actually markets them as the world’s most secure printers, a claim supported by their automatic recovery layers that shield against attacks.
In productivity and reliability, they’re built to handle heavy workflows: fewer interruptions, smart consumables management, easy fleet integration, and a three-year warranty. The expectation in a setting where a paused printer means lost work time.
The other big front is digitalization. The Flow lineup includes features that already pair with artificial intelligence, from Scan to Email to editable OCR on the device itself, and predictive printing and scanning experiences. The printer stops being just a sheet feeder and becomes the gateway for paper into the company’s digital workflow.
The frontier that hasn’t arrived yet
There’s a threat that isn’t yet operational, but already concerns long-term thinkers: quantum computing. And the risk isn’t just future. There’s a tactic known as “harvest now, decrypt later”: capture encrypted information today to decrypt it the day a quantum computer is capable of breaking the algorithms we currently deem secure.
Experts place the probability around 34% that this will happen by 2034, according to figures HP cites. Anticipating that scenario, the company has embedded quantum-resistant cryptography directly into the hardware of its printers. The LaserJet Pro 4000/4100 series is, in fact, the world’s first for small and medium businesses with this protection, according to HP itself. MuyComputerPRO has already covered that first wave of quantum-resistant printers.
It’s the Zero Trust logic extended to every device on the network: take nothing for granted, not even the corner printer, and prepare for what’s coming before it arrives.
From weak link to secure asset
For years, printer security has been the Achilles’ heel for many companies. Not for lack of resources, but because the printer rarely comes into the picture when threats are considered.
HP’s approach flips that idea: turning the most overlooked device into one of the best-protected, a fuller part of the company’s security ecosystem and one fewer attack surface to worry about. The printer stops being the service door someone forgot to close and starts playing on the defense side.
Secure your printing and protect your business
If your organization’s printing remains outside the security plan, now might be the time to revisit it. You can learn in detail about HP’s enterprise printing security, explore the LaserJet Enterprise lineup, or compare models in HP’s official store.
