ABSTRACT:
A printer using a paper supply roll is provided with a capability for conversion between snap-in loading of the paper roll, in which the roll is snapped into place with the tubular core of the paper roll being held to rotate between a pair of bearing members, and drop-in loading, in which the roll is dropped onto a support surface, against which the periphery of the roll then turns. In a first version, each of the bearing members has a flat side and a spherical side, which is turned inward for snap-in loading and outward for drop-in loading. In another version, the bearing members are moved inward for snap-in loading and outward for drop-in loading.
