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.

20 LPRINT CHR$(27); "G";30 LPRINT "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.
