A:Answer Thank you for the question. Printers don't need to be compatible with each other. For a printer to work with a computer it needs two things: a suitable physical connection and the correct software for the computer's operating system to communicate with the printer. The DeskJet 2755e is compatible with Windows 10, and Macintosh systems macOS v10.14 Mojave, macOS v10.15 Catalina, macOS v11 Big Sur. It is also compatible with the HP Smart App and Apple AirPrint.
