For mobile and cloud printing, it works with popular services such as AirPrint, Mopria, and likely any Canon mobile-printing solution — enabling printing directly from smartphones or tablets without needing a PC.

Canon Pixma Megatank Wireless Printer features a small monochrome LCD (1.35″) for basic control and settings — enough for essential tasks like checking ink levels or initiating simple print/copy jobs.
