HP (Ex HP Smart), formerly known as HP Smart, is an application for all of the company's products and services. The platform enables the printing and scanning of documents, monitoring ink and toner levels, and contacting customer support. If an HP printer is experiencing difficulties, users can place an order to replace it directly through the HP app. The app also allows users to run diagnostics and test the health of their device or battery, which can be helpful in identifying potential issues early on. The HP app also provides access to the cloud where documents are stored, allowing users to retrieve a printed document from their phone.
