The Epson dot graphics mode allows your GX-80 printer to produce
pictures, graphs, charts, or almost any other illustrative or creative
material you can devise. Instead of using the standard letters,
numerals, and symbols stored in the GX-80's ROM (Read Only
Memory), the graphics mode prints columns of dots on a line and
the picture is built up from the dots. For large pictures more than
one line will be necessary.
Justification
with NLQ
The NLQ (Near Letter Quality) mode offers a justification com-
mand that will give you four choices in the formatting of your text.
The command is <ESC> a followed by the ASCII code for one of
these numbers:
O
Left justification
1
Centering
2
Right justification
3
Fill justification
Left justification is the standard format, in which the left margin is
straight and the right margin is ragged. This is the way most type-
written pages look.
The centring command centres a line of text between the margins.
This is handy for headings, titles, and captions.
Right justification is the opposite of left justification. The right mar-
gin is straight and the left is ragged.
Fill justification puts extra spaces between words where necessary so
that both the left and right margins are even. This is the way most
magazines, newspapers, and books (including this one) are printed.
In using justification modes in the printer, you must send all charac-
ters to the printer one paragraph at a time. If you are using a word
processor, it will calculate the numbers of characters on a line and
split the words in the correct place. Thus you should not set justifica-
tion in the printer if your word processor is also set to use it, since
the two will conflict and you will not be able to predict the outcome.
When you use any of the justification commands, ensure that you
have set NLQ mode first.
