Epson FX-1050 User Manual page 87

Suppose you want to print the scientific symbol for the planet Mercury.
Although the FX has a number of special symbols, that is not one of
them. First, use a grid like the one below to plan where to place the dots.
Because the last two columns are reserved for the space between
characters, they are not included in the grid. And since most characters
do not use the bottom two rows, there is a heavy line to indicate the
usual lower limit for an FX character.
When you place your dots on this grid, remember that dots cannot go on
horizontal lines, but they can go on vertical lines. If they overlap other
dots, they will not be printed in draft, only in NLQ. As you design your
characters, draw the dots as large as the circles you see in the example
below. (The printer prints dots, but it is best to use circles when planning
your characters.)
