Abstract
Web medium supplies for a printer that uses a web medium on a core and printers are provided. In one aspect, the web medium supply has a frame with a first mounting support and second mounting support that are positioned along an axis of rotation. A first core mounting supports the core for rotation around the axis of rotation and a second core mounting supports the core for rotation around the axis of rotation. Rotation of the core is controlled by a first force applied to the first core mounting and a second force applied to the second core mounting that are both less than a third force that is sufficient to drive an alternative core against an inertial load of the core and web from one driven end.
