An ink jet printer (10) having a print head (14) for directing an ink jet toward a sheet of paper (16) includes automatic print head spacing apparatus (80) that holds the print head apart from the sheet of paper by a preselected distance. In a preferred embodiment, the printer includes a rotatable drum (20) for supporting the sheet of paper and media securing system (24) of a first predetermined thickness for securing the paper to the drum. The print head is positioned at the preselected distance after a major surface (130) of the print head engages and is pushed back by the media securing system.
