Emphasized works only in draft pica and NLQ modes. In elite and compressed the dots are already so close together that even with the reduced print speed, the LX-90 cannot fire, retract, and again fire the pins quickly enough to print overlapping dots. You do sacrifice some print speed with emphasized, because the print head slows down to print twice as many dots, but the increase in print quality is well worth it. Indeed, you may want to use emphasized instead of the NLQ mode for some purposes because emphasized printing is faster than NLQ printing. The code to turn off emphasized is ESCape "F". Double-Strike Another bold mode is double-strike. For this mode the LX-90 prints each line, then moves the paper up slightly and prints the line again. Each dot is printed twice, with the second one slightly below the first, as you can see if you run this program, which uses ESCape "G" to turn on double-strike. 5 PRINT CHR$(4);"PR#l" 10 PRINT "This is standard printing." 20 PRINT CHR$(27);"G"; 30 PRINT "This is double-strike printing." 100 PRINT CHR$(27);"@" 300 PRINT CHR$(4);"PR#0" This is standard printing. This is double-strike printing. Unlike emphasized, double-strike combines with any draft pitch (but not with NLQ) because it does not overlap dots horizontally. Since each line in this mode is printed twice, the speed of your printing is slowed. The code to turn off double-strike is ESCape "H". Some users prefer the effect of emphasized, and others prefer double-strike. You can look at the printout below and decide for yourself. This is standard printing, this is emphasized printing, and this is double-strike printing. 26

Emphasized works only in draft pica and NLQ modes. In elite and
compressed the dots are already so close together that even with
the
reduced print speed,
the
LX-90 cannot fire, retract, and again fire
the
pins quickly enough to print overlapping dots.
You do sacrifice some print speed with emphasized, because the
print head slows down to print twice as many dots, but the increase in
print quality is well worth it. Indeed, you may want to use empha-
sized instead of the NLQ mode for some purposes because emphasized
printing is faster than NLQ printing. The code to turn off emphasized
is ESCape “F”.
Double-Strike
Another bold mode is double-strike. For this mode the
LX-90
prints
each line, then moves the paper up slightly and prints the line again.
Each dot is printed twice, with the second one slightly below the first,
as you can see if you run this program, which uses ESCape “G” to turn
on double-strike.

30 PRINT "This is double-strike printing."
100 PRINT CHR$(27);"@"
300 PRINT CHR$(4);"PR#0"
This is standard printing.
This is double-strike printing.
Unlike emphasized, double-strike combines with any draft pitch
(but not with NLQ) because it does
not
overlap dots horizontally.
Since each line in this mode is printed twice, the speed of your printing
is slowed. The code to turn off double-strike is ESCape “H”.
Some users prefer the effect of emphasized, and others prefer
double-strike. You can look at the printout below and decide for your-
self.
This is standard
printing,
this is emphasized printing, and
this is double-strike printing.
