You see, folks are saying their HP Smart app is displaying the “ Printer status unknown ” error, suggesting the app is not able to communicate with the printer.

In addition, it will repair any rebadged icons and remove the HP Smart App (ironic name, that). That's all expected behavior, but you don't just download and run this program.
