1. A printer comprising:
a platen roller;
a bushing connected to the platen roller, the bushing having a wing extending radially from the bushing; and
a lower frame including:
a channel to receive the platen roller in an operational position in which the platen roller is configured to feed media for a print head of the printer;
an end piece defining an end of the channel, the end piece having an opening to receive the bushing when the platen roller is in the operational position; and
a tab on the end piece, the tab positioned to interface with the wing of the bushing to secure the bushing in the opening such that the platen roller is maintained in the operational position within the channel,
wherein the bushing is configured to rotate about a rotational axis of the platen roller between an unsecured position in which the wing extends from the bushing at a first side of the tab and a secured position in which the wing interfaces with the tab at a second side of the tab opposite the first side of the tab, and
wherein the tab comprises an entry surface at the first side of the tab, the entry surface angled to guide the wing past the tab as the bushing rotates from the unsecured position to the secured position.
