Enhancing Your Printing
You can obtain a wide variety of printing effects with the LQ-510,
from changing the number of characters per inch to using special
effects on selected words and phrases. This section gives you a
sampling of the features you may select with your software.
For software control of these features, see the instructions for your
application programs or look up their specific commands in the
Command Summary in Chapter 9.
Character Spacing
To add greater variety to your documents, the LQ-510 has three cpi
spacings, as well as proportional spacing. Each one can be selected
with a software command.
For each of the three built-in fonts, you can choose a character
spacing of 10, 12, or 15 characters per inch, or proportional spacing.
The printout below compares the three spacings:
This is 10 cpi printing.
This is 12
cpi printing.
This is 15 cpi printing.
As shown above, 15 cpi characters are only about two-thirds the
height of 10 and 12 cpi characters. This makes 15 cpi particularly
useful when you want to separate certain material from the main
text.
In fixed cpi spacing each character is given the same amount of
space. The width of proportional characters, however, varies from
character to character. For example, a narrow letter like i takes less
space than a wide letter like W. The width of each proportional
character is given in the Appendix.
