Unicode and Downloaded Fonts<br />
The <strong>Ithaca</strong>® <strong>610</strong> Printer supports Unicode encoding. This Unicode support is exclusive<br />
to the downloaded fonts.<br />
You must have downloaded and selected the downloaded font before you can reference<br />
the font via Unicode encoding. See the following group of commands for how to select<br />
and use a download font.<br />
There is a font downloading utility available from <strong>TransAct</strong>; contact your sales person or<br />
tech support for more information.<br />
WARNING: You must have proper rights to use a font in this manner.<br />
Do not download a font to the printer if you do not have the right to use<br />
the font as a downloaded printer font.<br />
The commands that control access to the downloaded fonts are all in the group that<br />
starts as ―[ESC]+‖ commands. Other commands that manipulate the resident fixed pitch<br />
fonts do not apply to the downloaded fonts described in this section. If commands that<br />
reference internal fonts or change the pitch are selected, the down loaded font will be<br />
deactivated and the last used internal font selected.<br />
To access characters located above 255 you must use a Unicode encoding method.<br />
Unicode Encoding<br />
UTF-16 is the most straightforward way to access characters above 255. UTF-16 is<br />
basically sending two 8-bit bytes that form a 16-bit address to access the desired<br />
character.<br />
UTF-16BE uses the big-endian method of sending the two bytes. This method sends the<br />
high byte first and then the low byte.<br />
UTF-16LE uses the little-endian method of sending the two bytes. This method sends<br />
the low byte first and then the high byte.<br />
UTF-8 uses a Multiple Byte Character Sequence (MBCS) to identify the desired Unicode<br />
character. This encoding method is less straightforward. This method uses unique bit<br />
sequences at the MSBs of a byte to determine its location and meaning within the MBCS<br />
encoding. See the table below for more information.<br />
Scalar Value 1 st Byte 2nd Byte 3rd Byte<br />
000000000xxxxxxx 0xxxxxxx<br />
00000yyyyyxxxxxx 110yyyyy 10xxxxxx<br />
Zzzzyyyyyyxxxxxx 1110zzzz 10yyyyyy 10xxxxxx<br />
