An apparatus and method for printing on both sides of a medium (34) by passing the medium (34) through a printing device (30) and printing on oppositely facing portions (66, 70) of the medium (34) during a single pass of the medium (34) through the printing device (30). Preferably, a first print head (50) prints on one portion while a second print head (54) prints on the other portion. The medium (34) is preferably folded so that after the printing is completed and the folded medium (34) is unfolded, the printed information (74) on one portion of the medium (34) correlates with the printed information (74) on the other portion of the medium (34). The printed information (74) is preferably data that has been measured with respect to time, and the printed data (74) on the oppositely facing portions (66, 70) correlate with respect to time. Preferably, the data is medical patient data in the form of textual data (78), physiological waveforms (74), or a combination of both. <IMAGE> |
