Function Initiate Unicode UTF-16BE Encoding
ASCII [ESC] + H
Hexadecimal 1BH 2BH 48H
Decimal <27> <43> <72>
Description The [ESC] + H command will put the printer into UTF-16BE character
encoding mode of operation. If you wish to access characters above
255, You must select a Unicode encoding such as UTF-16BE.
You must select a downloaded font, as described in this section, before
issuing this command.
UTF-16 is the most straightforward way to access characters above 255.
UTF-16 is basically sending two 8-bit bytes that form a 16-bit address to
access the desired character.
UTF-16BE uses the big-endian method of sending the two bytes. This
method sends the high byte first and then the low byte.
NOTE: All information sent to the printer must now use this encoding,
even for non-print commands.
Function Initiate Unicode UTF-16LE Encoding
ASCII [ESC] + L
Hexadecimal 1BH 2BH 4CH
Decimal <27> <43> <76>
Description The [ESC] + L command will put the printer into UTF-16LE character
encoding mode of operation. If you wish to access characters above
255, You must select a Unicode encoding such as UTF-16LE.
You must select a downloaded font, as described in this section, before
issuing this command.
UTF-16 is the most straightforward way to access characters above 255.
UTF-16 is basically sending two 8-bit bytes that form a 16-bit address to
access the desired character.
UTF-16LE uses the little-endian method of sending the two bytes. This
method sends the low byte first and then the high byte.
NOTE: All information sent to the printer must now use this encoding,
even for non-print commands.
