Administrative employees could need complete access to all printer features, whilst visitors might simply need the most basic printing capabilities.

Setting Up Access Controls

After defining the access levels, adjust the printer’s settings to implement access restrictions. The majority of modern printers give managers fine-grained control over user permissions, enabling them to define which individuals or groups can do specific tasks. To properly implement access controls, take advantage of features like role-based access control (RBAC), access control lists (ACLs), and user authentication.

Role-Based Access Control (RBAC)

Using RBAC, administrators can assign roles to individuals or groups according to their work duties or positions within the company. Roles like “administrator,” “printer operator,” and “guest user” should be defined, and each role should be given the appropriate permissions. This streamlines the permission assignment process and groups users with similar access requirements, making access control administration easier to handle.

Access Control Lists (ACLs)

ACLs offer precise control over printer resource access by defining rules that establish which users or groups are granted access and which are not. Establish Access Control Lists (ACLs) according to parameters like IP address, user identity, or time of day to limit access to particular services or functions. Make sure that ACLs are in line with organizational needs and security rules by reviewing and updating them regularly.
