Due to the majority of today`s multi-functional printer`s having wireless capabilities, it opens them up as an attack gateway and makes them susceptible to viruses and malware. In this post, we share the best security software you can employ to protect your printer, and ultimately your business.
Printers can serve as entry points for malware attacks. Hackers exploit vulnerabilities in printer software or firmware to install malicious software, jeopardizing the entire network`s security. Once inside your network, malware can spread to other devices, disrupt operations, steal data, or launch further attacks.
One way is through infected software. This happens more commonly when a printer is connected through a computer or a WiFi network, and installing infected software that way can cause it to get a virus.
Printers can store data and provide access to personal information and passwords. Printers pose security risks in several ways, including cloud printing and printers serving as an attack point for code. Printer security best practices can protect your devices, businesses and data from cybersecurity threats.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

A printer is actually a pretty smart computer. It has an operating system, runs software, and can activate a variety of actions, including malicious activity if commanded to do so. Even more so, the printer is a gateway to your network, but unlike on the endpoints – you can`t install an antivirus on your printer.
Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
An attacker controling a domain user/computer can, with a specific RPC call, trigger the spooler service of a target running it and make it authenticate to a target of the attacker`s choosing. This flaw is a “won`t fix” and enabled by default on all Windows environments (more info on the finding).
Almost all printers can print out a network configuration page, which will include the printer`s IP address. If your printer has a user interface (UI) display, the configuration page can generally be printed by going to the Settings or Setup page.
Un-authorized printing jobs− If your machine is printing unknown documents that nobody authorized, your printer may be compromised. Error messages− If your printer is displaying error messages or printing documents with error messages instead of the actual document, your printer may be corrupted.
Printers can be hacked both physically and remotely. An attacker can insert a flash drive infected with malware into a printer, giving them control of the printer and potentially the devices connected to it. However, this means that a hacker would need direct access to the desired printer.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Click on Device Manager from the context menu. In Device Manager, click on View and select Show hidden devices. Next, expand the Printers section to view your printer.
“Printers are often entrusted with credentials to other resources on your network, like file servers and email servers,” said Tom Pohl, LMG`s Penetration Testing Team Manager. By hacking printers, adversaries can gain access to sensitive data, elevate privileges, and even compromise your cloud environment.
The typical conventional models of printers, also called copiers did not have any security. However, due to rising endpoint cybersecurity threats in the business environment, most of the recent models have built-in security features.
Over time dirt and dust accumulate inside the printer, which affects it`s functionality. Cleaning a printer regularly can prevent a low print quality or damage to the device.
No. “Printing to PDF” essentially captures an image of the website and none of the code contained within it. That said, before visiting a website like that you should likely make sure that your browser isn`t vulnerable to whatever malware it`s distributing.
In Settings, go to Network & Internet, find Network and Sharing Center, go to Change advanced sharing settings and uncheck Turn on automatic setup of network connected devices. Alternatively, if you have Network Discovery disabled the same result happens. This applies to all user profiles on the workstation.
Printer Emulations are on-printer apps that allow Print DNA capable printers to use a variety of printer command languages, while adding the benefits of manageability and security. Multiple emulations can be downloaded to a single printer, allowing users to choose between command languages as needed.
Viruses can`t corrupt or damage USB ports, but they can use USB ports as a way to spread and infect other systems. Viruses can also disable the computer`s ability to communicate with USB ports.
Anything that can write itself to memory can in theory save itself without any user interaction. By this definition you could say Windows itself is malware because anytime you plug in a drive or usb, it writes a few invisible bytes that could contain anything.
Just like computers, printers have volatile memory (RAM) that is removed when you turn the printer off. Volatile memory requires power to store the information. Deleting volatile memory is easy: Simply shut down or unplug your printer for a minute or so.
Unplugging the power cord while the ON lamp is lit or flashing may cause drying or clogging of the print head and print quality may be reduced. If the power cord is unplugged, the date/time settings will be reset and all documents stored in the printer`s memory will be lost.
