[QUESTION] ESC/POS Firmware 1.06 vs 03.01 #1313
Comments
Even when I use your example 1:1, I've got the same message: <?php
/* Call this file 'hello-world.php' */
require 'vendor/autoload.php';
use Mike42\Escpos\PrintConnectors\FilePrintConnector;
use Mike42\Escpos\Printer;
$connector = new FilePrintConnector("/dev/rfcomm0");
$printer = new Printer($connector);
$printer -> text("Hello World!\n");
$printer -> cut();
$printer -> close(); |

Hi
I use your project since a couple of years for a project of myself where we print some stuff via a Raspi Zero to an EPSON TM-P20.
Epson just released a new version of this printer, EPSON TM-P20II. The prints stopped working on the new printer - my guess is, it's the new firmware (see picture attached).
There's a tech reference for ESC/POS commands (https://download4.epson.biz/sec_pubs/pos/reference_en/escpos/index.html), but I have a hard time finding the reason, why exactly my prints do not work again.
May I ask you, if you have an idea, in which direction I should search? I can provide further project info, logs or whatever is needed anytime.
Thank you in advance!
Sam
