To use PHP with raw ESC/POS, you can use the fsockopen() function to connect to the printer and then send the raw ESC/POS commands directly to the printer.

Here is an example of a PHP script that uses raw ESC/POS to print a simple receipt:

PHP

$printer_ip = '192.168.1.100';
$printer_port = 9100;

$socket = fsockopen($printer_ip, $printer_port);

if ($socket) {
// Send the ESC/POS commands to the printer
fwrite($socket, chr(0x1B) . chr(0x40)); // Initialize the printer
fwrite($socket, chr(0x1B) . chr(0x61) . chr(0x01)); // Select the font
fwrite($socket, "This is a sample receipt.\n");
fwrite($socket, chr(0x1B) . chr(0x69)); // Cut the paper

// Close the socket
fclose($socket);
} else {
// Could not connect to the printer
}

To use this script, you would need to replace the $printer_ip and $printer_port variables with the IP address and port number of your printer.

You can also use the fsockopen() function to send more complex ESC/POS commands to the printer, such as commands for printing barcodes, images, and coupons. You can find more information on the ESC/POS protocol in the Epson ESC/POS Command Reference.

Here is an example of a PHP script that uses raw ESC/POS to print a barcode:

PHP

$printer_ip = '192.168.1.100';
$printer_port = 9100;

$socket = fsockopen($printer_ip, $printer_port);

if ($socket) {
// Send the ESC/POS commands to the printer
fwrite($socket, chr(0x1B) . chr(0x61) . chr(0x01)); // Select the font
fwrite($socket, chr(0x1D) . chr(0x6B) . chr(0x49) . chr(0x1E)); // Set HRI position
fwrite($socket, chr(0x1D) . chr(0x6B) . chr(0x45) . chr(0x1E)); // Set barcode width
fwrite($socket, chr(0x1D) . chr(0x6B) . chr(0x48) . chr(0x1E)); // Set barcode height
fwrite($socket, chr(0x1D) . chr(0x6B) . chr(0x47) . chr(0x02)); // Set barcode type
fwrite($socket, "1234567890"); // Print the barcode
fwrite($socket, chr(0x0A)); // Newline

// Close the socket
fclose($socket);
} else {
// Could not connect to the printer
}

To use this script, you would need to replace the $printer_ip and $printer_port variables with the IP address and port number of your printer. You would also need to replace the 1234567890 barcode string with the barcode string that you want to print.

You can use the fsockopen() function to send any ESC/POS command to the printer. This gives you a lot of flexibility in terms of what you can print. However, it is important to note that you need to have a good understanding of the ESC/POS protocol in order to use raw ESC/POS effectively.
