Assigning the character data with the IBM mode

Fundamentally, the process to define and print downloaded NLQ character with the IBM mode is the same as for draft characters, except that you must supply about four times as much character data, and you must design the character with the two passes of the print head in mind.

Use the grid in Figure 5-6 to help plot the data with the IBM mode. Due to the two-pass process, NLQ characters can contain up to 16 dots vertically.

Figure 5-6. Use this grid (or one similar to it) to define your own NLQ characters with the IBM mode

To make the character data easier to calculate, put the first pass dots with black circle on the grid when you are designing your characters, and the

second pass dots with white circle. Remember that adjacent dots may not - overlap on the same pass; in other words, if one dot is in a box, its adjacent

dot on the same pass may not be on a line. Therefore, to make smooth characters, put the dots needed to overlap any spaces in a character in the appropriate places in the second pass grid.

If we plot our car-shaped symbol for NLQ, the grid data will look like Figure 5-7.

The defining process is the same as for draft characters, except that you must select NLQ mode, and you must define 46 data. If you wish to print your
