The down-line loading of characters is the printer feature which allows the
definition of special characters not present in the character sets. Do not forget to
select the BUFFER FULL function in the Printer Setup procedure. The
parameters in the command have the following meaning:
{n} {m} are the two decimal numbers that define the first and the last characters
to be replaced in the character set in use. If you want to replace only one character,
{m} must be equal to {n}. Any value in the range {0} to {127} will accepted even
if it is advisable not to define the code {32}, which is the space character.
{w0} are the numbers that specify the width of the character and the space around
it. The space on the left of the character (in dots column) is specified by {w0)
while the space on the right of the character is specified by {w2}. The {w1}
parameter specifies the number of columns of dots that must be printed to design
the character
See the following table for the maximum value of {w0}, {w1}, {w2}:

d0..dn are the data of the character that is printed. Three bytes are needed for
each column because it is composed of 24 dot positions. In this way, the number
of data bytes is {w1} * 3. You can define character in superscript or subscript
printing, two bytes are needed for each column because it is composed by 16 dot
positions; the number of data bytes is {w1} * 2.
