Install lightweight PHP service on the computer to handle the print job from Web Browser

  1. Download "Laragon" from this LINK or our fixed archived HERE


  2. Execute the installer downloaded, first option ONLY chose "Run Laragon when Windows Starts", rest uncheck.
  3. Once installation is complete, it should start Larafon in your "Taskbar"
  4. Double click to open the interface, if the service started, chose "Stop", we'll need to do some quick configuration to Laragon


  5. One-Stop, select the gear icon on the top right of the windows to configure the Laragon
  6. In "General" you should have the setting as follow, except for the "Document Root" and "Data Directory", rest should follow as highlighted
  7. Under Service & Ports, make sure have following service also. Important is the Apache port with "8888"

  9. Once configured, just save by closing this "Preferences" windows with "x" icon on top right.
    Then you shall "Start All"
  10. If all is correct, you should have this in the Laragon window.
  11. Now we'll put an "index.php" file into the "Root" Directory. Open the WWW root directory by clicking the "Root" Icons
  12. It will open your directory root folder windows and should only have 1 file called "index.php"


  13. Right-click open the index.php and "edit" with notepad.exe

  14. Once you have the file open, remove all the contents in the file and replace them with the following codes:

    <?php
header('Access-Control-Allow-Origin: *');
$printer = "\\\\localhost\\RETAIL-LABEL-PRINTER";
$CMD = $_REQUEST['CMD'];
if($CMD != "") {
	$tmpfname = tempnam(sys_get_temp_dir(), 'LBL');
	file_put_contents($tmpfname, $CMD);
	$newname = str_replace(pathinfo($tmpfname, PATHINFO_EXTENSION), 'prn', $tmpfname);
	rename($tmpfname, $newname);
	copy($newname, $printer);
	unlink($newname);
}
  15. Now Laragon can "close" and it shall be hiding in the taskbar and automatically startup with Windows by default.
  16. Save it and that all, you can "test" it by calling from browser: http://localhost:8888/ and should have the following screen.

    This is fine because we are waiting for the label print command from the Retail Label Printing program.

You shall be able to make some printing with the printer now from the Retail Print Program.
