A multifunction printer can hold employee records, customer invoices, contracts, scanned IDs, and payroll documents - often with less oversight than a laptop or server. This office printer security guide gives business teams a practical way to protect those documents without making everyday printing harder for staff.
The goal is not to turn every office printer into a complex IT project. It is to identify where documents, credentials, and device settings are exposed, then apply controls that fit the size of your office and the sensitivity of what you print.
Why office printers create a security gap
Networked printers are computers with paper trays. They connect to your Wi-Fi or wired network, receive files from multiple users, may scan documents to email or cloud folders, and can store job data on internal memory or a hard drive. An unattended print job is also a physical exposure: a confidential document left in an output tray can be read by anyone passing through.
The risk rises with multifunction devices that print, scan, copy, and fax. For example, an HP LaserJet Enterprise MFP M528 or Brother MFC-L6900DW can support busy workgroups efficiently, but the same features that improve productivity also require sound access and configuration practices.
Security should be balanced with usability. A five-person office with one printer may need a strong administrator password, automatic firmware updates, and a simple secure-release process. A multi-location organization handling personnel or customer information may need network segmentation, user authentication, centralized reporting, and a formal device retirement procedure.
Office printer security guide: start with the basics
A short device inventory is the most useful first step. Record each printer's make, model, serial number, physical location, IP address, network type, and primary administrator. Include the cartridge used by each machine. This helps procurement avoid ordering errors, such as confusing the HP 89A and high-yield HP 89X cartridges used in compatible LaserJet models, while also giving IT a clear view of active devices.
Remove printers that are no longer in service from the network. Old devices are easy to overlook, especially after an office move or department change. If a printer has no defined owner, no current firmware support, or no business need, disconnect it rather than leaving it available by default.
Change default credentials and limit administrator access
Default passwords are a common and preventable weakness. Change the device administrator password during setup, store it in the company's approved password-management process, and limit who can modify network, email, address-book, and firmware settings.
Employees generally do not need administrator access to print. Give staff the least access necessary, while ensuring there is a documented backup administrator so a vacation or staff departure does not create downtime. Review access after role changes, particularly for employees who previously managed office operations or IT.
Keep firmware and print drivers current
Printer firmware patches can address known security issues, improve network reliability, and correct operational defects. Establish a recurring review schedule, then apply updates during a low-volume period. For larger fleets, test an update on one representative device before deploying it broadly. This reduces the chance that a driver, print server, or workflow application is disrupted unexpectedly.
Use manufacturer-supported drivers and remove unused print drivers from workstations and print servers. Old drivers can create both security and compatibility problems. A standardized driver approach is especially valuable when several departments use the same printer model.
Protect documents before they reach the output tray
The most visible printer security failure is also one of the most common: sensitive pages sitting in a shared tray. Secure print, sometimes called pull printing or held print, keeps a job in the device queue until the user enters a PIN, taps a badge, or authenticates at the printer.
This control is particularly useful for HR, legal, healthcare-adjacent, accounting, and executive teams. It also cuts waste. Staff can delete a job they no longer need instead of printing it and leaving it behind. The trade-off is a small extra step at the device, so secure release is most effective when the authentication method is quick and the printer is located near the users who rely on it.
For smaller offices without a full pull-print platform, enable PIN-protected jobs for sensitive documents and place printers away from reception desks, public areas, and unrestricted hallways. Set a policy that uncollected jobs are removed promptly. A locked print room may be appropriate for payroll, tax, or employee files, but it is not necessary for every routine document.
Secure the network and scanning functions
A printer should not sit on the same unrestricted network as every employee device, guest device, and visitor connection. Where your network supports it, place printers on a dedicated segment and allow only the systems and ports required for printing, management, and scanning. Disable protocols and services your organization does not use, such as older file-sharing methods, wireless direct printing, or remote management features.
If the printer offers web-based administration, require encrypted HTTPS access and restrict management to authorized network locations. Avoid exposing printer management interfaces directly to the public internet.
Scanning deserves equal attention. Scan-to-email and scan-to-network-folder features can route highly sensitive files beyond the printer itself. Use dedicated service accounts with only the permissions required, protect email credentials, and review address books regularly. If a departing employee's personal email address remains programmed into a device, remove it. For shared folders, make sure scanned files do not automatically become visible to a wider department than intended.
Treat printer supplies as part of operational security
Toner cartridges do not usually hold your document data, but supply purchasing still affects business continuity. A failed cartridge, incorrect model, or unreliable delivery can force staff to shift work to unsecured or less controlled devices. Standardizing supplies by printer model helps prevent those last-minute workarounds.
Confirm the exact printer model before ordering. For example, Brother TN850 and high-yield TN880 cartridges are used across several compatible Brother laser models, but a cartridge should always be verified against the specific device. Likewise, offices using HP LaserJet Enterprise models should confirm whether their printer takes HP 89A, 89X, or another cartridge family rather than relying on a similar-looking model number.
Compatible toner can be a practical cost-control option when it is sourced from a business-focused supplier that provides compatibility assistance and warranty coverage. The buying decision should account for page yield, expected print volume, print-quality needs, and the cost of an interruption - not only the upfront cartridge price. High-yield replacements and multipacks can reduce reordering frequency for heavily used devices, provided storage is clean, dry, and organized by model.
At Advanced Business Technology, businesses can use compatibility support to confirm cartridge selection before placing repeat or bulk orders. Keeping approved cartridge SKUs in a purchasing list also helps prevent staff from substituting an incorrect supply when toner runs low.
Create a controlled process for device moves and retirement
Printers are often moved, replaced, leased, returned, or sent for repair without a clear handoff. That is a risk because device memory, address books, scan destinations, and stored jobs may remain on the machine. Before a printer leaves your control, remove it from the network, delete stored jobs and contacts, reset the device according to the manufacturer's procedure, and document the action.
For devices with internal storage, confirm whether the model supports encryption, secure erase, or hard-drive removal. A factory reset may not be sufficient for every device or every compliance requirement. If your organization handles regulated information, involve IT or a qualified service provider before disposal, return, or resale.
Give staff a policy they can follow
A printer policy does not need to be long. It should tell employees how to release sensitive jobs, where confidential printouts belong, who can request a new device or cartridge, and what to do if a printer displays unusual behavior. It should also state that staff should not connect unknown USB drives, change network settings, or forward scanned documents to personal accounts.
Review these expectations during onboarding and whenever a new multifunction printer is deployed. A secure configuration only works when employees understand the few actions expected of them.
The strongest printer security program is usually the one people can maintain: known devices, current firmware, restricted access, protected print release, and reliable supply planning. Start with the printer that handles your most sensitive documents, then apply the same disciplined process across the rest of the fleet.
