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-80 cannot fire, retract, and again fire the pins quickly enough to print overlapping dots. You do sacrifice some print speed and ribbon life 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 emphasized instead of the NLQ mode for some purposes because emphasized printing is faster than NLQ printing. Now that you have seen our example of emphasized printing, we will give you a master program that allows you to test almost any of the ESCape codes, including the ESCape code to turn on emphasized: ESCape "E". Master program First, type in the program below. If you have some programming experience, you can see that the program asks you what codes you want to test and then prints a sample of what the codes do. Be sure to type in the blank spaces in lines 70 and 80. If you are using Applesoft™ BASIC, see Appendix F. 20 PRINT "Which ESCape code do you II 30 INPIJT "want to test";A$ 40 PRINT "What kind of printing ( 50 INPUT "does it produce";B$ 60 LPRINT CHR$(27)A$ 70 LPRINT "This sample uses ESCape ";A$ 80 LPRINT "to produce ";B$;" printing." 90 LPRINT CHR$(27)"@" Now run the program. When the first question appears on the screen, type a capital E and then press the RETURN key. Type "emphasized" and press the RETURN key in answer to the second question. The program is easy to use. Just remember to press the RETURN key after the answer to each question and to use a capital letter in the answer to the first question unless we tell you to use a lowercase letter for a specific code. 42

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-80 cannot fire, retract, and again fire the
pins quickly enough to print overlapping dots.
You do sacrifice some print speed and ribbon life 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 emphasized instead of the NLQ mode for some purposes because
emphasized printing is faster than NLQ printing.
Now that you have seen our example of emphasized printing, we
will give you a master program that allows you to test almost any of
the ESCape codes, including the ESCape code to turn on empha-
sized: ESCape “E”.
Master program
First, type in the program below. If you have some programming
experience, you can see that the program asks you what codes
you want to test and then prints a sample of what the codes do. Be
sure to type in the blank spaces in lines 70 and 80. If you are using
Applesoft™ BASIC, see Appendix F.

PRINT
"Which

PRINT

Now run the program. When the first question appears on the
screen, type a capital
E
and then press the
RETURN
key. Type
“emphasized” and press the
RETURN
key in answer to the second
question. The program is easy to use. Just remember to press the
RETURN
key after the answer to each question and to use a capital
letter in the answer to the first question unless we tell you to use a
lowercase letter for a specific code.
