This wrapper class is a gift for my blog readers. I think the class is self descriptive. This is why I ain’t write how to use it bla bla bla…You can make pcl and ps files from html with this class. I have submitted this class at phpclasses too. You may have a look by clicking HERE. It runs both on Windows and *Nix envioronment.

html2pcl class starts here:

class Html2pcl {

    public $device = 'laserjet'; //alternatively you may use 'epson' etc as printers
    public $paperSize = 'a4'; //alternative you may use 'letter' etc as papersize

    function __construct(){
        //checking whether the directory named "out" already exists or not
        if(!file_exists("pcl_output")){
            mkdir("./pcl_output", 0755);
        }

        //checking whether the directory named "ps_output" already exists or not
        if(!file_exists("ps_output")){
            mkdir("./ps_output", 0755);
        }
    }

    function __destruct(){
        //Clearing file status cache
        clearstatcache();
    }

    function isWinServer()
    {
        return !(strpos(strtoupper($_SERVER['SERVER_SOFTWARE']), 'WIN32') === false);
    }

    //please don't use $htmlFileName without "http://" rather use like this "http://www.google.com"
    //please use $pclFileName without the extension like "google"
    function makePCL($htmlFileName, $pclFileName){
        $file = './pcl_output/'.$pclFileName.'.pcl';
        if($this-&gt;isWinServer()){
            //checking whether the file name given as parameter is already exists or not
            if(!file_exists($file)){
                exec("perl html2ps $htmlFileName &gt; ./ps_output/".$pclFileName.".ps");
                exec("gs -sDEVICE={$this-&gt;device} -sPAPERSIZE={$this-&gt;paperSize} -sOutputFile=./pcl_output/$pclFileName.pcl -dNOPAUSE -q ./ps_output/$pclFileName.ps -c quit");
            }
        }
        else{
            if(!file_exists($file)){
                exec("html2ps $htmlFileName &gt; ./ps_output/".$pclFileName.".ps");
                exec("gs -sDEVICE={$this-&gt;device} -sPAPERSIZE={$this-&gt;paperSize} -sOutputFile=./pcl_output/$pclFileName.pcl -dNOPAUSE -q ./ps_output/$pclFileName.ps -c quit");
            }
