Assigningthe characterdata with the IBM mode

Fundamentally,the processto defineandprintdownloadedNLQ character withthe IBMmodeis the sameas for draftcharacters,exceptthat youmust supplyaboutfour times as much characterdata, and you must design the characterwith the two passesof the printhead in mind.

Use the grid in Figure5-6 to helpplotthe data with the IBMmode. Dueto the two-passprocess,NLQ charactemcan containup to 16dotsvertically.

Figure S6. Use this grid (or one similar to it) to define your own NLQ characters with the IBM mode

To make the characterdata easier to calculate,put the first pass dots with black circle on the grid when you are designingyour characters,and the secondpass dots with whitecircle. Rememberthat adjacentdots may not overlapon the samepass;in otherwords,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 neededto overlapany spacesin a characterin the appropriateplaces in the secondpass grid.
