Description:
------------
I've written a PHP Script, which prints Bills automatically. Now for each printed Site there will be about 120kb lost. This memory is now on the apache.exe process. If i paint serveral 100 Sites, this a huge prolem. The Server will be out of Memory.
The right Script is different i've cutted it down to the necessary code.

Reproduce code:
---------------
<?php
 $handle = printer_open("PrinternameOrAddress");
  printer_start_doc($handle, "PrintTitle");
  printer_write($handle, "test");
  printer_end_doc($handle);
  printer_close($handle);
?>

Expected result:
----------------
Page is printed and memory is free after it,

Actual result:
--------------
Page is printed but the apache.exe needs more memory for each page.
