Publication number: 20220032631Abstract: A print device may include a refill interface, a processor, and a computer readable medium. The refill interface may have an electrical interface for transmission and reception of signals between the print device and a refill container. And the computer-readable medium may have instructions stored thereon that when executed by the processor are to cause the processor to fetch signals, via the electrical interface of the refill interface, from the refill container indicative of a licensed print functionality of the print device. The instructions may also be to enable the licensed print functionality on the print device responsive to the fetched signals and to maintain the licensed print functionality enabled subsequent to detachment of the refill container.Type: ApplicationFiled: December 4, 2018Publication date: February 3, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Jefferson P.
