Who is using my printer?

Hy, help me pls, how can I view who had acces to my printer or my computer in the last 24hours? my computer is on of a local network computer, and someone has printed on my printer. The printer is installed on my computer through an usb cable. To be able to print my partner from the same office I have shared the printer on the network. The problem is that someone else than my partner is printing through the network on my printer.
