Draft mode characters

As you have seen, draft characters are designed on a grid which is 24 dots high by 9 dots wide (plus up to three columns of dots for space between characters). User-defined draft characters print at the same high speed as normal draft characters, even though they may print with more dots and may even be designed for proportional spacing.

There is, however, one restriction on designing characters for draft printing. Dots in the same row may not print in adjacent columns. That is, there must be an empty dot position to the left and to the right of each dot that prints (the space on either side of the character counts as an empty dot position). Therefore, in a character grid that is nine dots wide, a maximum of five dots will print in any row.

For vertical spacing, there is no such restriction. You can print a solid column of 24 dots if you wish.

Letter quality characters

If you select letter quality printing with the <ESC> “x” 1 command, you can design your user-defined characters on a grid which is 24 dots high by 15 dots wide. Each character can be as wide as 18 dots, including space on either side of the character. The dot columns are spaced closer together horizontally than draft style dot columns (the horizontal dot spacing is l/180-inch when printing pica width-as opposed to l/120-inch for draft characters).
