PHP Printer functions

I am attempting to change the orienation of printing for a page with a huge table to landscape instead of portrait. This is the code I used: $defprintercon=printer_open(); printer_set_option( $defprintercon, PRINTER_ORIENTATION, PRINTER_ORIENTATION_LANDSCAPE); printer_close($defprintercon); When extension=php_printer.dll is remarked out, I get an error message saying that the function printer_open() is undefined, but when I leave the dll in, it simply will not open the page (hangs forever). Any advice is appreciated. J. Wharton PHP
