Figure 2 from WJE/Haupt [77]; CLICK IMAGE to magnify

This is Figure 2 from the WJE/Haupt article, showing the three printing methods for easy comparison. Notice the center example, from 405 Accounting Machine, exhibits the "jaggies" typical of vertical typebars (CLICK HERE for more about typebars), or slight misalignment of page on the first and second printing passes. The bottom example is from the Card-Operated Table Printer, for which the sans-serif Bell Gothic font was chosen (originally developed by Mergenthaler Linotype for printing telephone directories); notice the thin spacing between some of the columns and the perfect vertical and horizontal alignment. Thanks to Herb Grosch for this scan.
