Support Armenian language

[levon1991]

Hi Mike When will you add support Armenian language?

I read about that in your forum https://github.com/receipt-print-hq/escpos-printer-db/issues/31 but it is 2 year ago.

Hi @levon1991 - any solution involving printer profiles will be highly printer-specific, can you share some information about which hardware and OS you are using?

I can basically confirm that this example will only get you a string of "??????" on the default profile, which is what you would use for Epson printers.

<?php
/* Call this file 'hello-world.php' */
require __DIR__ . '/vendor/autoload.php';
use Mike42\Escpos\PrintConnectors\FilePrintConnector;
use Mike42\Escpos\Printer;
$connector = new FilePrintConnector("php://stdout");
$printer = new Printer($connector);
$printer -> text("Կրնամ ապակի ուտել և ինծի անհանգիստ չըներ\n");
$printer -> cut();
$printer -> close();

However, if you need this to work and are prepared to work with something that is prototype-quality, then I would suggest reading this blog post. I have never finished working on custom font support, but you can absolutely print Armenian on a good ESC/POS printer.

You can clone the code here, and get unifont here. You need to locate unifont-12.1.03.tar.gz, and extract font/precompiled/unifont-12.1.03.hex.

You then set a path and some text -

diff --git a/unifont-bitmap-font/unifont-example.php b/unifont-bitmap-font/unifont-example.php
index 374431c..e1ef080 100644

And you can go printing receipts with basically any character set on them, just without image, correct spacing, or other luxuries :)

$ php unifont-example.php > /dev/usb/lp0

This is all on an Epson TM-T20II on Debian, but maybe it will also be useful in your setup.

I try to run this script and want to print in terminal but it printed this

if it can't print in termianl I assume it wouldn't print in pos printer to.

I change this

•    $unifont = "/usr/share/unifont/unifont.hex";
  

•    $unifont = "unifont-12.1.03.hex";
  

and this -$text = file_get_contents("php://stdin"); +$text = "Հայերեն ֏55,000\n"; by your example. can you halp us sort it out?

@levon1991 - The command I ran redirected that binary to /dev/usb/lp0, which is where my TM-T20II printer appears (it is connected via USB).

Can you share some information about the type of printer you have, and how it is connected? I should be able to point you in the right direction if it's something common.

type of my printer SP-POS888U, now I can print check in armenian language but I have problem with hade of text what I can do to fix this problem

[levon1991]
