php_printer.dll not setting options

Hi, I have a couple issues with the php_printer.dll extension that I'm hoping you can help out with. The good news is that I can print just fine to a network printer. The bad news is I can't seem to get it to accept printer_set_options for anything. Detail below. Environment: WAMP (consisting of PHP 5.1.6, Apache 2.0.59, MySQL 5.0.24a) running on a Windows Server 2003. Code: <?php $testdoc = "I wish this printed correctly"; $handle = printer_open("My Printer"); printer_start_doc($handle, "Note"); printer_set_option($handle, PRINTER_MODE, RAW); printer_set_option($handle, PRINTER_COPIES, 2); printer_set_option($handle, PRINTER_ORIENTATION, PRINTER_ORIENTATION_LANDSCAPE); printer_write($handle, $testdoc); printer_end_doc($handle); printer_close($handle); ?> Issue 1.) The output prints successfully but doesn't print in Landscape. Issue 2.) If I pause the print queue on the server and run the script, I see 2 documents - 1 is 1 page long and 1 has N/A for pages. It looks like this even if I remove the entire line for copies. So basically, it appears as if the printer commands work but don't pick up any of my printer_set_option options. What am I messing up? Thanks, Drew
