Time Line for Windows maps all background colors on plotters to white in order to conserve pen ink, avoid possible pen damage, and save time. This means that white text on a dark background will not be visible on plotted output. Therefore, if you have an Time Line for Windows file that was initially created with background colors for another printing device, and you need to output to a plotter, choose the Print Black & White option on the Print dialog box to ensure that all your text shows up.
