Plotting and charting functions can be performed with a band printer by adding dot-producing elements in a rastered pattern on the band at a pitch equal to or greater than the product of hammer settle time and band-velocity. Fig. 1 illustrates a print band 1 having both engraved characters 2 and dot-producing elements 3, each with a respective, uniformly spaced timing mark 4. Elements 3 extend above and below the height of characters 2 to address vertical points in an array a sixth of an inch high. The rastered pattern may be repeated several times around the band. Horizontal spacing of elements 3 can be done either by providing a fixed horizontal distance between each element 3 and its timing mark 4, or by having groups of elements spaced at several different distances relative to their respective timing marks.
