A paper dispenser dispenses paper sheet by sheet. Paper projects from a dispenser housing in an operational position so that it can be pulled off from a supply roll by hand. The paper dispenser has a delivery roller driven by the web of paper that is being pulled. A stop which is moved from a rest position to a blocked position against the force of a return spring blocks the rotation of the delivery roller so that the sheet is torn off due to the pulling power, and is slowed down by a braking device when returning to the rest position. A post-delivery device is configured to further drive the delivery roller once the sheet has been torn off and completes the rotation in a time-delayed manner so that the paper projects from the dispenser housing and can be pulled again.
