A page buffer for receiving and holding, in queue, pages prepared by a printer and subsequently processed by mailpiece inserter. The page buffer includes pairs of vertically-aligned rollers defining a plurality of page stations therebetween. Each pair of rollers is spaced-apart and defines a nip for driving printed pages along a feed path. Furthermore, each page station is defined by and between a first pair of rollers disposed downstream of an adjacent second pair of rollers. A drive means is also provided for independently driving the pairs of vertically-aligned rollers. The drive means is controlled such that, in a first operating mode, the pairs cooperate to drive printed pages along the feed path. In a second operating mode, the drive means is controlled such that at least one of the page stations causes its respective first pair of rollers to retain and hold a leading edge portion of a printed page while the adjacent second pair drives and releases a trailing edge portion of the printed page. The printed page is, therefore, held within the page station such that the trailing edge droops below the feed path in a predominantly vertical orientation.
