Abstract

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