When checking the Printer Supplies History report, it is observed that the 'Initial Cartridge Level' and 'Last Known Level' columns show an 'Unknown' status instead of a percentage value.

The capability to report the cartridge level varies from printer to printer, and you may observe different behaviors for different types of Lexmark devices.
