I'm using the lastest version of XAMPP for Windows (1.7.4). For a PHP project, I've to do an application to print a PDF document in server. For do it, I'm using Foxit Reader. With the command "exec" of PHP, I'm executing the command of Foxit Reader for printing. All is Ok if Apache is executed as application, but when I use Apache as service, printing is done regardless of the configuration of the printer. For example, the quality of the printing is not the same that I've configured.
