The following guide is to help understand the techniques available for sending a specialized character encoding to a printer device which does not recognize UTF-8. This is for raw printing only.

Background

Character encoding, also known as a "codepage" or sometimes "character map" is a raw byte representation of a language's character set. It's much like a custom font with the letters in (what would appear to be) incorrect places.

Why would someone use a codepage instead of UTF-8? Well, put simply, most people wouldn't if they had a choice however the thermal printing industry (as well as several others) still has good, reliable hardware in the wild that doesn't offer UTF-8 support. Chances are if you've received a receipt from a restaurant, store or gas station, it was printed in a raw codepage for your language. For the US, this is often CP-1252, or more formally called Windows-1252.

Java 7 supports about 130 encoding formats which reside in lib/rt.jar and lib/charsets.jar. Choosing the correct codepage is often dependent on strict requirements such as hardware limitations but each character set will have some history behind it which may help understand its usefulness to you or your company.

Character sets often start with CP-xxxx, UTF-xxxx, IBM-xxxx or ISO-xxxx although may have less-obvious names such as Big5 (Traditional Chinese), TCVN-3-1 (Vietnamese), etc. Also, despite a device claiming a character set is supported, the diacritical marks may be incorrectly implemented for a particular language such as CP-1258, or may not render properly due to right-to-left style languages, such as Arabic.


ESCPOS

The following section is written for ESCPOS capable printers. Due to hardware and firmware differences, not all encodings and fonts are available on all ESCPOS compatible hardware. Please consult your hardware manufacturer for determining compatibility.

ESCPOS Western European

Covers French, Spanish, Italian, Portuguese, German

var config = qz.configs.create("Printer name", { encoding: 'Cp1252' });   // Toggle Cp1252 in Java 
/* If 1252 does not work and you get strange characters, try 'Cp850'; The Epson TM-T20 programming guide, for example, claims to support Cp1252, but it actually supports Cp850*/

var data = [
   /* Toggle WPC1252 in ESCPOS */
   '\x1B' + '\x74' + '\x10',   // ESC t 16 = Cp1252
  // '\x1B' + '\x74' + '\x02',   // ESC t 2 = Cp850

   /* Sample French */
   'Voix ambiguë d\'un cœur qui, au zéphyr, préfère les jattes de kiwis\n',

   /* Sample Spanish */
   'Tendré que ir a España. ¿Cómo? Por avion.\n',

   /* Sample Italian */
   'L\'articolo è “uno”. Uno scontrino, perché? Perché la parola inizia per s più consonante.\n',

ESCPOS Arabic

Since 2.0.8

Instruct an Epson printer to use IBM864 codepage. Note, this lacks most of the Arabic diacritics which are used in Modern Standard Arabic as well as Dialectal Arabic as well as some additional letters, however, these are often omitted, so IBM864 should be suitable for Arabic characters.

For the Epson printer to recognize IBM864, we had to use a utility to change settings in the printer. More details about this is available here: #339

var config = qz.configs.create("Printer Name", { encoding: "IBM864" });  // Toggle IBM864 in Java 

var printData = [
   '\x1B' + '\x40',   // ESC @ - init command, necessary for proper byte interpretation
   '\x1B' + '\x74' + '\x25', // Setup "codepage 37", which is Epson's IBM864
   'لكن لا بد أن أوضح لك أن كل هذه الأفكار', '\n', // UTF-8 RTL text
   '\x1B' + '\x69'          // cut paper
];

qz.print(config, printData);

ESCPOS Russian

var config = qz.configs.create("Printer Name", { encoding: 'Cp866' });

var data = [
   /* Toggle Cp866 in ESCPOS */
   '\x1B' + '\x74' + '\x11',   // ESC t 17 = Cyrillic #2 (Cp866)

   /* Sample Russian Text */
   'Быстрая коричневая лиса прыгает через ленивую собаку.\n';
];

qz.print(config, data);

ZPL

ZPL Simplified Chinese

Requirements:

  • Zebra Printers using Unicode compatible x.14 firmware (or later) and the 64MB Flash Memory Option
  • A Unicode compatible font set for printing Simplified Chinese characters is installed - for more information on installing fonts on a Zebra printer, refer to Installing Fonts on a Zebra Printer
    • This example uses the Andale Simplified Chinese font set (P/N 56080-001)

Note: The printer will not permanently store the Font Assignment command (^CW) or Encoding table command (^SE) -- if the printer powers off, these settings are lost. Send both of these commands at the beginning of every format or you can use an Autoexec file, which automatically sends these settings when the printer is powered on: ^XA^DFE:AUTOEXEC.ZPL^CW1,E:ANMDS.TTF^SEE:GB.DAT^XZ

var config = qz.configs.create("PrinterName");

var data = [
   '^XA\n',
   '^SEE:GB.DAT^CI28\n', //^SE = set the encoding table & location; ^CI28 = change encoding to UTF-8
   '^CW1,E:ANMDS.TTF\n',     //^CW = set the font identifier & location (Andale font)
   '^FO50,50\n',
   '^A1,50,50\n'
   '^FD Chinese Andale 盒呆艾丙^FS\n',
   '^FO50,200\n',
   '^A1,50,50\n',
   '^FD Zebra 盒呆艾丙^FS\n',
   '^XZ\n'
];

qz.print(config, data);
