Super/Subscript Printing In Wrong Horizontal |

WordPerfect® 5.1 for DOS
Problem
Symptoms: A customer's IBM Proprinter XL24 printer is not consistently printing superscript and subscript characters. These characters do not print in the correct horizontal position. Solutions: This is a situation that may occur on several printers such as all models of the IBM Proprinters, the Star NX 1000, and the IBM Quietwriters. The problem occurs because 10cpi fonts use 1/10 of an inch for the motion units, and 17cpi fonts (or any other pitch) use the motion that corresponds with their pitch (i.e., 17 pitch uses 1/17 of an inch spacing unit). The reason that this causes a problem is because WordPerfect formats the line with the regular text at 10cpi, and a superscript character needs to be placed at .1 inches. Since the superscript character is 17cpi, the closest it can be placed is at either 1/17" or 2/17", neither of which is going to look exactly right. WordPerfect is forced at this point to round to the nearest position, and thus the term "Rounding Error." This is a limitation of printers that use this type of spacing and may be seen not only in superscript and subscript, but also in small caps, or any other time two different pitch fonts are used on the same line. This may also occur on the IBM Quietwriters. |
