Adding the Numero Symbol to ZPL code

You may need to install a font to get symbols that are not in the fonts that are pre-installed.  I'm fairly sure that none of the standard pre-installed fonts for US printers have that symbol.  If you recieved a printer for Europe or Asia, it might have additional fonts pre-installed.  You can print a font list by sending:

^XA^WDE:*.FNT^WDE:*.TTF^WDZ:*.FNT^WDZ:*.TTF^XZ

The UTF8 encode of Numero Sign (№) is 0xE2 0x84 0x96. You need to use the proper encoding in the ZPL in order to printer. The following example should print the Numero Sign for you.

^XA
^CI28
^FO10,30
^A0,20,20
^FH^FDNumero Sign = _E2_84_96^FS
^XZ
