A3 - RAM usage
If A3 is OFF, the printer is able to store patterns repre-
senting characters that you have defined with the Epson
or IBM printer commands (see Chapter 7). If A3 is ON,
the printer can store the data it receives from the com-
puter. This speeds up the printing process. However, it
cannot store user-defined character patterns.
A4 - Color and zoom
If A4 is ON, you can print in color and use the zoom fea-
ture. If it is OFF, these features are unavailable. If you
change this setting after saving settings using the macro
function (see page 62), the current Zoom setting will be
cancelled.
A5 - Auto line feed
If A5 is ON, your computer needs to send both a line
feed code and a carriage return code at the end of each
line. Most applications will do this automatically. If A5 is
set to OFF, the printer will automatically perform a line
feed each time it receives a carriage return. As a result,
your software only needs to send a carriage return at
the end of a line.
If your output is double-spaced when it should not be,
you may need to set this setting to ON.
If a line of your output is printed on top of another line,
you should set this setting to OFF.
Bl - Graphics direction
When the printer prints graphics rather than text, it can
either print bi-directionally (the print head prints as it
moves from left to right and again as it returns from
right to left), or uni-directionally (the head prints from
left to right only). Bi-directional printing is faster, while
uni-directional printing may give higher-quality output.
If Bl is ON, bi-directional printing is selected. If Bl is
OFF (the default setting), uni-directional printing is
selected.
