Defines and downloads to RAM (temporary memory) bit image data for
one or more characters. Before downloading characters, use the
configuration menu to set the printer to accept downloaded characters.
The format for downloading characters is shown here. Additional
information on designing, storing, and printing download characters is
given on the preceding pages.
In the Download Character command, m specifies whether the characters
are selected for printing, or downloaded but not selected. This parameter
performs the same function as the Select Character Source and Library
command, SOH Az%, and that command may be used at any time to
change the setting made here. This setting may also be changed using
the "Overlay Characters" option on the configuration menu. The following
are valid settings for m:
m = 0: Download but do not select
m = 1: Download and select immediately
n1 and n2 specify the range of data byte values to which the download
characters are assigned. Data must be sent for each character in the
range specified by n1 and n2. To download only one character, send the
same data.
