Star Micronics NP-IO manual Vertical

six boxes ,wide by nine boxes high.

•Horizontally, dots may be centered in a box, or may straddle a line, making the actual character grid 11 dots wide by 9 dots high. Vertically, dots can only be centered in a box. See Figure 6-2.

•The minimum width of a character is five dots.

•Unlike standard characters that are restricted to a height of seven dots, user-defined characters may use eight dots vertically.

•Dots cannot overlap - that is, you may not have a dot

inside a box next to one that is on a line.

•You may define any position between ASCII 32 and 127.

L	Photocopy the grid in Figure 6-3 to help design your new
c	characters. We will use			a tiny	representation			of a chemist’s flask
	for our example. We decided that our flask will not be a
L	“descender”	(printing		below		the	baseline		of	standard
	characters), so a figure “1” is written next to Descender on the
L	grid. If your character			is a	descender,			write	a “0” next to
	Descender.
	Next we calculate		the	vertical		numerical		values	of the	columns
i	of dots. and enter them underneath the grid. For example, look-
	ing at Figure	6-4, we see that			in the		left-most		column	there is

Ii.. only one dot, and it is sitting in the “2” box. Thus its vertical
