Abstract
A method and apparatus for managing filters in a filter pipeline in a print driver used with an image production device. The method may include configuring a filter pipeline in a print driver with one or more proxy filters, each proxy filter including logic to invoke an associated processing filter to perform functions similar to a corresponding processing filter alone, and enabling the print driver to be at least one of certified and digitally signed with the proxy filter without the associated processing filter being known or present.
