In a print group for an ink printing apparatus, a housing is provided with print bars comprising print heads. The print bars are moveable independently of one another in a vertical direction from a printing position adjacent to a printing substrate into a park position and back. A protective flap bar for each print bar is provided which is pivotable and which is open to one side. The protective flap bar is arranged in a vertical position next to the print bar in the printing position such that the open side is facing away from the print bar. The protective flap bar is arranged in a horizontal position with the open side upward in the park position such that the print bar is engaged with its print head side in the protective flap bar.
