Note that printer_set_option will not work due to a bug in php_printer.dll. As far as I can tell this extension has been abandoned for quite some time.

Warning :
PRINTER_FORMAT_LETTER = LETTER 8.5x11
PRINTER_FORMAT_LEGAL = LEGAL 8.5x14
If your printer uses custom paper size, printer_get_option will return an unpredictable code.
