Abstract
A printer for printing individual sheets from a continuous feed roll includes a housing configured for receipt of a feed roll of sheet material, and a print mechanism disposed within the housing, whereby the sheet material is conveyed within the housing to print mechanism. A sheet separating device is disposed within the housing downstream of the print mechanism to separate the sheet material into individual printed sheets. A discharge assembly is disposed downstream of the sheet separating device and defines a gap through which the sheet material is advanced. At least one protruding member is disposed in the gap at a position so as to contact and deflect the sheet material and to impart a curved transverse profile to a trailing edge of a first individual sheet held in the gap. In this manner, a leading edge of a subsequent sheet bisects the curved trailing edge of the first sheet and pushes the first sheet out of the gap as the second sheet is advanced through the print mechanism.
