1 . Make sure you send only plain text (no html is allowed)
2. Depending on the printer you use , you may need to configure the printer driver

There are two options

1. If you buy off-the-shelf printer, you will need to connect it to a computer with thunderbird installed and configured for automatic printing.

2. Our printers, does not need a computer, just connect to the internet and automatically print.

look at this post for resolution

We havent received any complaints related to the version of the PHP used.

You can check to see what is going on by enabling wordpress debugging

1. In your WP-config.php file add the following:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', false );
define( 'WP_DEBUG_LOG', true );

2. In your theme functions.php add the following function:

if (!function_exists('write_log')) {

    function write_log($log) {
        if (true === WP_DEBUG) {
            if (is_array($log) || is_object($log)) {
                error_log(print_r($log, true));
            } else {
                error_log($log);
            }
        }
    }

}

3. Uncomment the tho lines that contain the following in plugins/woo-instant-notifications/admin/class-wcnotifications-instance.php

$data=$this->object->get_data();
write_log($data);

Then make a test order.

And you can paste the contents of the file /wp-content/debug.log here

What’s the version of the plugin that you are using?

According to this something has modified your php plugin file adding empty lines before or after the begining of the php plugin file.

Removing the empty lines should solve the issue for you.
