So, for some reason, you do not want to connect the printer directly to the laptop. To connect to the printer via another computer means creating a network, which requires a piece of equipment called a router. Also, both the laptop and the PC will have to have Ethernet capability, which may require installing a Network Interface Card in one or both of them. The printer will have to be configured as a network printer, which requires allowing sharing in the Network Folder on the Control Panel. Then, after you have established your network, you will have to install a network printer on to the laptop. This is done by double clicking on the 'Network Neighborhood' icon on the desktop, then right-clicking on the icon for the printer and selecting 'Install'.
