Final answer:
In property law, the printer is not a fixture since it can be removed easily without damage, while the fan likely is a fixture because it's integrated into the building and its removal would cause harm.
Step-by-step explanation:
The question posed concerns whether the printer and fan installed by Melanie in her leased commercial space are considered fixtures. In the context of property law, a fixture is personal property that has been attached to land or a building and becomes part of the real property. The printer, being easily removable and not causing harm to the premises, would likely be considered personal property. However, the fan, which is built into the wall and the removal of which would leave a hole in the exterior wall, is more likely to be considered a fixture as it is integrated into the structure of the building.
