CompTIA PDI+ Certification validates the knowledge and skills necessary to support printing and document imaging devices including printers, copiers, scanners, multi-functional devices and fax machines. It is a vendor-neutral certification that recognizes a technician's understanding of basic electromechanical components and tools, print engine and scan processes and components, color theory and connectivity/networking. The exam also covers soft skills such as customer service, professionalism, safety and environment. While there are no prerequisites for the certification exam, it is recommended that entry-level candidates have foundation-level knowledge or hands-on experience working with printing and document imaging devices. CompTIA PDI+ is also relevant for more seasoned technicians in the printing and document imaging industry interested in an industry-accepted credential that validates their knowledge and skills.
