Help on PHP extensions

I'm new to PHP so there may be an obvious answer: How do you load dynamic dll extensions????? I'm using windows 2000 with apache I'm trying to use the printer extensions In php.ini I set the following: enable_dl = On Tried the following extension_dir commands in php.ini extension_dir = c:/PHP/extensions/ extension_dir = 'c:/PHP/extensions/' extension_dir = c:/PHP/extensions extension_dir = "c:/PHP/extensions/" Plus others --- All the extension dll's are in C:/PHP/extensions without any security. when I un-comment the following in php.ini extension=php_printer.dll and then run PHP I get the following error: ----------------------------- Unable to load dynamic library 'c:/PHP/extension/php_printer.dll' - The specified procedure could not be found. ----------------------------------- I get the same error when using dl('php_printer.dll'); in a php program. Help!!!! How do i get these to load. Thanks for the help.. Dan
