Epson FX-286 - Impact Printer, Руководство пользователя

Страница: 83 / 223

Line 30 begins a loop to produce multiple print lines. Lines 40 and
50 were explained previously. Lines 70 and 80 are similar to lines 40
and 50 except
that
line 80 uses a reversal of the patterns in line 50. As
the loop is executed, the program prints lines 50 and 80 alternately so
that the patterns of the print lines will fit together well.
Notice that the graphics command can be in effect for only one
print line. The command is in lines 40 and 70
so that
it is issued each
time a new print line is begun. To print more than one line of graphics,
the graphics command must be issued before
each
line.
Line
100
is
the
reset code to return the printer to its defaults.
Density Varieties
Although all the examples so far in this chapter have been in the
singledensity graphics mode, the FX-286 offers seven other eight-pin
density modes and two for nine-pin. Nine-pin graphics (Epson mode
only) is not
necessary
for most uses, but you can find the command
(ESCape “^“) in Appendix G. All the eight-pin densities and their com-
mands are described in Table
6-1.
