Density Varieties

Although all the examples so far in this chapter have been in the single-density graphics mode, the LX-90 offers five other eight-pin density modes and two nine-pin ones. Nine-pin graphics is not necessary for most uses, but you can find its command (ESCape "^") in Appendix B. All the eight-pin densities and their commands are described in Table 8-1.

Table 8-1.Graphics modes

		Alternate
Mode	Density	code	Description
0	Single	ESC “K”	60 dots per inch;
			480 dots per 8” line
1	Low-Speed	ESC “L"	120 dots per inch;
	Double		960 dots per 8” line
	High-Speed	ESC “Y”	Same density as Mode 1,
2	Double		but faster; does not print
			consecutive dots in a row.
3	Quadruple	ESC “Z”	240 dot positions per inch; 1920
			dots per 8” line; does not print
			consecutive dots in a row.
4	CRT	none	80 dots per inch;
	graphics		640 dots per 8” line
	One-to-one	none	72 dots per inch;
5	(plotter)		576 dots per 8” line; produces
			the same density horizontally as
			vertically
6	CRT	none	90 dots per inch;
	graphics II		720 dots per 8” line

You are familiar with the command format that uses the ESCape code and a letter, but LX-90 graphics commands can also be in the following format:

LPRINT CHR$(27)"*"CHR$(m)CHR$(n1)CHR$(n2);

with m being the mode number found in the left column of Table 8-1. As usual, nl and n2 reserve the number of columns for graphics. The seven modes include six densities, with two speeds for double-density.
