7245A

The 7245A was a long-axis thermal graphics printer. It was both a standard raster printer and an HP-GL vector plotter (the paper moved in both directions when in plotter mode). This sprocket-feed printer could plot images up to 200 feet long (7.4 inches wide). It had a raster graphics print resolution of 106 dots per inch and a vector graphics step size of 0.016mm, better than HP pen plotters of the time. The 7245A printed raster characters in a 9 x 12 dot cell at a speed of 38 characters per second.
