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 and prints 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

The other 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.

10 LPRINT "This is standard printing."

20 LPRINT CHR$(27)"G";

LPRINT "This is double-strike printing."

100 LPRINT CHR$(27)"@"

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.
