SNMP Ports for Printers: What to be Aware of When Using Printer Management Tools

Simple Network Management Protocol (SNMP) is widely used for managing networked printers. The protocol communicates over designated ports, which can impact the security of the printers and the data they handle. For many this might be a bity nerdy or even boring area, buts its important to understand that it can introduce security risks if not managed properly.

This blog post will discuss the SNMP ports for printers and what organizations should be aware of when using printer management tools.

SNMP Ports

SNMP uses two designated ports for communication: 161 for SNMP requests and 162 for SNMP traps. The use of these ports is standardized, making it easy for organizations to manage their printers. However, these ports also make printers more vulnerable to attack, as they can be targeted by attackers looking to access the printers and steal sensitive information.

What to be aware of when using Printer Management Tools

Organizations should be aware of the potential risks associated with using SNMP when using printer management tools.

Here are some things to keep in mind:

  1. Security of the communication channel: Organizations should ensure that the communication between the printers and the management system is secure. This can be achieved by encryption and authentication, such as the ones available in SNMP version 3.

  2. Configuration of SNMP: Organizations should configure SNMP securely, using strong community strings and limiting access to authorized users. Additionally, they should avoid using the default "public" community string, which is well-known and easily targeted by attackers.

  3. Monitoring SNMP traffic: Organizations should monitor SNMP traffic, looking for any unusual activity that may indicate a security breach. This includes monitoring for unauthorized access attempts, changes to the configuration of printers, and sending SNMP traps.

  4. Updating printer management tools: Organizations should keep their printer management tools up to date, ensuring they have the latest security features and patches. This will help to reduce the risk of vulnerabilities being exploited by attackers.


In conclusion, organizations should be aware of the potential risks associated with using SNMP for printer management. By following best practices and using secure tools, they can reduce the risk of unauthorized access and data breaches, protecting their printers and the sensitive information they handle.

Using a printer management tool like 3manager MPS software, makes it possible easily support multiple SNMP communities.
