OWNLOAD DOUBLE BYTE FONT
Download a single band of a double byte font characters to the printer. If the download is successful, an
ACK will be returned. If unsuccessful, a NAK will be returned.
If multiple font character bands are to be downloaded, the font name, code page selection, width, and
height must be the same for all download commands. The start address of each command should be greater
than the start address of the preceding download command.
The font name is used to identify the font. It will be printed on the diagnostics or configuration form. When
a downloaded font is to be deleted, the font name is used to identify the font.
Only one double byte font can be downloaded into the printer at any given time. An existing double byte
font needs to be deleted prior to downloading a new double byte font.
