How to Stop Sensitive Documents Sitting in Printer Output Trays
A document left unattended in a printer output tray may appear harmless, but it can become a significant security risk for businesses.
Printed documents often contain sensitive information including:
- Customer records
- Financial information
- Legal documents
- Employee information
- Healthcare records
- Contracts and confidential business data
When documents are printed immediately and left waiting at a shared printer, anyone walking past the device may be able to view, collect, copy or remove that information.
This is known as unclaimed print risk — a common document security issue caused by traditional “print and collect later” processes.
Key takeaway:
The most effective way to stop sensitive documents sitting in printer trays is to use secure print release, where documents are only printed when the authorised user authenticates at the device.
Why Are Documents Left in Printer Output Trays a Security Risk?
Traditional printing works like this:
- A user sends a document to the printer.
- The printer immediately produces the document.
- The document sits in the output tray.
- The user collects it later.
This creates a security gap between sending and collecting the document.
During this time, documents may be:
- Viewed by unauthorised employees
- Accidentally collected by another person
- Photographed or copied
- Forgotten and left exposed
- Removed without permission
For organisations handling confidential information, the printer output tray becomes an uncontrolled document storage location.
What Types of Sensitive Documents Are Commonly Exposed?
Almost any printed document can create risk, but common examples include:
Financial Documents
- Invoices
- Payroll information
- Financial reports
- Tax documents
- Banking information
Legal Documents
- Contracts
- Court documents
- Client information
- Confidential agreements
Human Resources Documents
- Employment records
- Performance reviews
- Salary information
- Personal employee details
Healthcare Information
- Patient records
- Medical information
- Referral documents
- Prescription information
Business Strategy Documents
- Proposals
- Pricing information
- Customer presentations
- Internal reports
The Problem With Traditional Office Printing
Many businesses still rely on a “trust-based” printing model:
“The person who printed the document will collect it.”
However, in busy workplaces this often fails because:
- Employees get distracted
- Meetings interrupt workflows
- Multiple people use the same printer
- Documents are forgotten
- Users accidentally print to the wrong device
As workplaces become more open, collaborative and mobile, organisations need stronger controls over how documents are released.
What Is Secure Print Release?
Secure print release is a printing security process that holds documents in a secure print queue until the user confirms their identity at the printer.
Instead of printing immediately:
- The user sends a document to print.
- The document is securely held.
- The user authenticates at the printer.
- Only then is the document released and printed.
Authentication methods can include:
- PIN codes
- Employee ID cards
- Usernames and passwords
- Mobile authentication
- Network credentials
This ensures confidential documents are collected only by the person who requested them.
Benefits of Secure Print Release
1. Prevents Documents Being Left in Printer Trays
The biggest benefit is simple:
Documents are not produced until someone is physically present.
This eliminates abandoned print jobs and reduces the chance of confidential information being exposed.
2. Improves Document Confidentiality
Secure print ensures sensitive documents reach the intended recipient.
This is particularly important for:
- Legal firms
- Healthcare providers
- Financial organisations
- Government departments
- Education providers
3. Reduces Printing Waste
Many documents printed today are never collected.
Secure printing helps reduce:
- Forgotten print jobs
- Duplicate printing
- Accidental printing
- Paper waste
- Toner consumption
4. Supports Compliance Requirements
New Zealand organisations have responsibilities to protect personal information under the Privacy Act 2020.
While printer security is only one part of information protection, secure printing supports broader privacy practices by reducing unnecessary exposure of printed information.
How Secure Printing Works in a Modern Workplace
Before Secure Print
Employee prints document → Printer immediately outputs document → Document waits in tray → Anyone nearby can access it
After Secure Print
Employee prints document → Document held securely → Employee authenticates → Document prints securely
This small workflow change creates a significant improvement in document control.
Other Ways to Protect Sensitive Printed Documents
Secure print release is one important control, but organisations should also consider:
Printer Authentication
Require users to verify their identity before accessing printer functions.
Examples:
- Staff ID cards
- Login credentials
- PIN authentication
Printer Placement
Avoid placing printers in:
- Public reception areas
- High-traffic walkways
- Uncontrolled spaces
Position devices where authorised employees can access them safely.
Automatic Document Deletion
Modern multifunction printers can automatically remove temporary stored document data to reduce exposure risk.
Printer Hard Drive Security
Business printers may store temporary copies of scanned and printed documents.
Security controls should include:
- Data encryption
- Secure deletion
- Storage protection
Employee Awareness
Staff should understand:
- Do not leave printed documents unattended
- Collect documents immediately
- Dispose of confidential documents securely
- Report incorrect print destinations
Industries Where Secure Printing Is Essential
Legal Firms
Law firms regularly print:
- Client documents
- Agreements
- Court information
- Confidential correspondence
Secure print helps maintain client confidentiality.
Healthcare Organisations
Healthcare providers handle highly sensitive personal information.
Secure printing supports safer management of:
- Patient records
- Medical documents
- Referrals

Schools and tertiary organisations print:
- Student records
- Assessment information
- Staff documentation
Secure printing helps protect student and employee information.
Financial Services
Banks, accountants and financial advisers handle:

Frequently Asked Questions
How do I stop confidential documents being left at printers?
The most effective solution is secure print release, which holds documents in a secure queue until the authorised user authenticates at the printer.
What is secure print release?
Secure print release is a security feature that prevents documents from printing immediately. Instead, documents are stored securely until the user verifies their identity at the printer.
Why are printer output trays a security risk?
Printer output trays are a security risk because documents may contain confidential information and can be viewed, collected or removed by unauthorised people before the intended recipient retrieves them.
Are printers a cybersecurity risk?
Yes. Modern printers are connected network devices that can store information, communicate with business systems and access sensitive documents. They should be managed as part of an organisation’s cybersecurity strategy.
Does secure printing reduce paper waste?
Yes. Secure printing reduces abandoned print jobs because documents are only printed when the user is present and ready to collect them.
Is secure printing required under the NZ Privacy Act?
The Privacy Act 2020 requires organisations to take reasonable steps to protect personal information. Secure printing is one control that can help reduce the risk of unauthorised access to printed information.
