Need help with COM

[Andy-H]

Hi, I have coded a COM script that opens an InternetExplorer.Application (browser) object and navigates it to a page, I currently have it printing via the printer (php_printer.dll) library after a screen capture using imagegrabscreen but I can't get the document positioned correctly on the printer. I was wondering if anyone knows if you can use COM to instantiate a PrintDocument object and print the HWND of a browser object.

 

 

Here is my code:

 

 

<?php
  function print_img($doc,$img,$res,$pos_x,$pos_y)
    {
     $img_size = getimagesize($img);
     $img_resolution = $res;


     $img_width = $img_size[0];
     $img_height = $img_size[1];


     $ptr_resolution_x = printer_get_option($doc, PRINTER_RESOLUTION_X);
     $ptr_resolution_y = printer_get_option($doc, PRINTER_RESOLUTION_Y);


     $img_scale_x = $ptr_resolution_x / $img_resolution;
     $img_scale_y = $ptr_resolution_y / $img_resolution;


     $ptr_width = $img_width * $img_scale_x;                            
     $ptr_height = $img_height * $img_scale_y;
  
     printer_draw_bmp($doc,$img,$pos_x,$pos_y,$ptr_width,$ptr_height);
    }


$browser = new COM('InternetExplorer.Application');
//$printer = new COM('PrintDocument.Application');


$handle = $browser->HWND;
$browser->Navigate('http://www.phantom.uk.net');
$browser->Visible        = true;
$browser->FullScreen     = true;
$browser->TheaterMode    = true;
$browser->ToolBar        = false;
$browser->MenuBar        = false;
$browser->AddressBar     = false;
$browser->StatusBar      = false;


while ( $browser->ReadyState != 4 )
{
    com_message_pump(1000);
}


$img = uniqid('img_');
$png = $img . '.png';
$bmp = $img . '.bmp';
sleep(3);
$im = imagegrabscreen();//($handle, 0);
imagepng($im, $png);
$browser->Quit();


`convert {$png} -resize 500% {$bmp}`;/*
    $ph = printer_open('Dell Color Laser 1320c');
        printer_start_doc($ph, "Test Document");
        printer_start_page($ph);
            print_img($ph, $bmp, 96, 0, 0);
        printer_end_page($ph);
        printer_end_doc($ph);
    printer_close($ph);*/
    
    //unlink($png);
    //unlink($bmp);
    die('Done!');


?>

 

 

Any help is appreciated.

 

 

Thanks.

Still no luck with this, anyone have any idea if it's possible to implement a PrintDocument COM object using PHP? Ideally I want to pass the printing responsibility to the InternetExplorer.Application object and override the alertbox somehow. Perhaps there is a way to create a keypress event for CTRL + P? An ActiveX solution?

 

 

This is all new to me and I hate COM already lol I wish there was an idiot proof manual for PHP COM objects :/

 

 

Thanks for any help.

OK I managed to get this working, here is my code:

 

 

<?php
try
{
   $browser = new COM('InternetExplorer.Application');
   $handle  = $browser->HWND;
   $browser->Navigate('http://www.phantom.uk.net');
   $browser->Visible        = false;
   $browser->FullScreen     = true;
   $browser->TheaterMode    = true;
   $browser->ToolBar        = false;
   $browser->MenuBar        = false;
   $browser->AddressBar     = false;
   $browser->StatusBar      = false;


   while ( $browser->ReadyState != 4 )
   {
       com_message_pump(1000);
   }
   sleep(5);
   $browser->ExecWB(6,2); // print document, dont prompt user.
   sleep(5);
   $browser->Quit();
}
catch (com_exception $e)
{
   echo $e->getMessage();
}
?>

I commented the code, in case anyone wants to use it. It is intended to be used as an AJAX request, will successfully print a document to a windows servers default printer. It requires the CURL extension and you may need to change WAMP and

Browser configuration utility services settings allowing them to interact with desktop (im not 100% sure about this tho.
