eight of them in a single user-defined character. The design in Figure 6-5 uses the top eight, but you can also use the bottom eight by using the grid on the right as explained later in this section. Once the character is planned on the grid, you simply add the pin values for each column together, just as you do for graphics. Then, the next step in defining a character is to send this information to the printer. Sending the character definition The command to define characters is complex: ESC & 0 nl n2 al dl.. . dn You can define more than one character with a single command. The values nl and n2 are the ASCII codes of the first and last characters you are defining. If you are defining only one character, nl and n2 are the same. You can use any codes between 32 and 127 or 161 and 254 decimal for nl and n2, but it is best not to define decimal 32, which is the code for a space. You can also use other codes by using the ESC 6 and ESC I commands (see the Command Summary). An example will show how to specify nl and n2. If, for instance, you want to redefine the characters A to Z, nl is A (or ASCII code 65) and n2 is Z (or ASCII code 90). So the command ESC & 0 AZ (followed by the appropriate data) would replace the entire alphabet of capital letters. Figure 6-5. Design grids 6-14 Graphics and User-defined Characters

eight of them in a single user-defined character. The design in Figure
6-5 uses the top eight, but you can also use the bottom eight by using
the grid on the right as explained later in this section.
Once the character is planned on the grid, you simply add the pin

printer.
Sending the character definition
The command to define characters is complex:
ESC & 0 nl n2 al dl.. . dn
You can define more than one character with a single command. The
values
nl
and
n2
are the ASCII codes of the first and last characters you
are defining. If you are defining only one character,
nl
and
n2
are the
same. You can use any codes between 32 and 127 or 161 and 254
decimal for
nl
and
n2,
but it is best not to define decimal 32, which is
the code for a space. You can also use other codes by using the ESC 6
and ESC I commands (see the Command Summary).
An example will show how to specify
nl
and
n2.
If, for instance, you
want to redefine the characters A to Z,
nl
is A (or ASCII code 65) and
n2
is Z (or ASCII code 90). So the command ESC & 0 AZ (followed by
the appropriate data) would replace the entire alphabet of capital letters.
