Abstract: Disclosed are a paper storage and a printer. The paper storage comprises: a warehouse body (20) for accommodating a medium, a medium outlet (A), and a roller (5) arranged on the storage body (20), wherein the medium outlet (A) is configured to discharge the medium accommodated in the storage body (20) after the medium passes by the roller (5), and an opening (224) opposite to the roller (5) is also arranged on a wall of the storage body (20), to allow an external medium processing device to match with the roller (5) through the opening (224) to process the medium. To replace the paper storage in a printer adopting such paper storage, the need for respective detachment of various parts of the paper storage, and the need for opening of the upper cover of the printer to load the paper roll are eliminated, thereby avoiding the problems of complex operations of replacing the paper roll and inconvenience in use.
