I've personally not used ESC/POS Print Driver for PHP library but the documentation does state the use in a fairly detailed way. Judging by your images, you have a printer shared from a server called \\Sah-it\ARP-808K. To connect (guessing the printer is an Epson), it's advised you do the following:

    use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;
    use Mike42\Escpos\CapabilityProfile;
    $profile = CapabilityProfile::load("simple");
    $connector = new WindowsPrintConnector("smb://Sah-it/ARP-808K");
    $printer = new Printer($connector, $profile);

Note: Suitable for Epson TM-series printers so check documentation to ensure your printer is supported

If your having issues with the above via hostname, then check your PHP servers DNS configuration as it may not be able to resolve Sah-it. In this instance I would suggest trying to connect via IP to the printer (if networked) or to your print-server's IP using the following:

use Mike42\Escpos\PrintConnectors\NetworkPrintConnector;
use Mike42\Escpos\Printer;
$connector = new NetworkPrintConnector("10.x.x.x", 9100); //Printer/Server IP
$printer = new Printer($connector);
try {
    // ... Print stuff
} finally {
    $printer -> close();
}

if you have further issues then add your printer make and model, confirm your Webserver can resolve \\Sah-it and add any relevant errors which may help.
