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.
