Abstract

A method is described for preventing background stripes in text printed on a serial printer. Serial printers print a horizontal row of data, then index and print the next horizontal row of data. How well the two rows of data line up is dependent on the index accuracy. If the index does not go far enough, there is a slight overlap between the two rows of print. If the index goes too far, then there is a space between the lines. If the two lines were supposed to come together, as in a drawing rule, then a slight overlap will hardly be noticeable because the print is the same color. However, extra space will look like a stripe of the paper color showing through. The term "drawing rule" is an instruction to draw a vertical or horizontal line of specified width.
