Quadruple-Density Graphics Mode
The FX also gives you the ability to print dots four times as densely
as in Single-Density. Change the 1 line 20 to a 3 and lines 30 and 50 to
read:
20 A$=CHR$(27)+"*"+CHR$(3)+CHR$(50)+CHR$(0)
30
B$=CHR$(85)+CHR$(42)
50

QUADRUPLE-DENSITY GRAPHICS
In Quadruple-Density Graphics Mode, any FX can print 480 times 4
(or 1920) columns of dots on a single 8-inch line and the FX-100 can
print 816 times 4 (or 3264) columns on a 13.6-inch line. The graphics
setting required to fill an entire &inch line in this mode is n
1
equals 128
and n
2
equals seven (since 7 times 256 plus 128 equals 1920).
At this density the same limitation as for High-Speed Double-
Density Graphics Mode applies-you can’t print two adjacent dots in
the same row.
More densities
Yes, there are more densities. Besides the three graphics densities
we’ve covered so far (Single, Double, and Quadruple), the FX can
print in two graphics densities that match the screen densities of two
types of CRTs. One of these may allow you to develop designs and
then print them in the same weight. Additionally, the FX can simulate
the density that plotters use-called one-to-one aspect ratio. This
mode prints the same density horizontally as vertically, 72 dots per
inch each way, which allows you to print true circles.
You can print a sample of all the modes with the following program:
10 FOR M=0 TO
6
20 A$=CHR$(27)+"*"+CHR$(M)+CHR$(l20)+CHR$(0)
30 B$=CHR$(85)+CHR$(42)
50 LPRINT "MODE # ";M;" ";
60 LPRINT A$;:
FOR X=1 TO 60: LPRINT B$;: NEXT X
70 LPRINT: NEXT M
80 LPRINT CHR$(27)"@"
