Abstract
A system and method are provided for securely accessing imaging job resources in a printing device. The method initially downloads a restricted software resource to a printing device. That is, the resource is restricted to use by a user group. As differentiated from factory installed software, or field upgrades, the restricted software resource is stored in a user-accessible memory, such as non-volatile storage (e.g., RAM). Subsequently, an imaging job is accepted for processing. The imaging job is verified to be associated with the user group. Subsequent to verification, access is permitted to the restricted software resource, and the imagining job is processed using the restricted software resource.
