We have developed a PHP script to build PDF's and send emails which then get called from an RPG program using QP2SHELL. For our developer users the errors go to the standard PHP error log, but for our customer's users it's printing on their default printer. Our developer profiles use *WRKSTN as the printer, and of course the users have an actual printer device. Is there a way to prevent this from printing through either RPG or PHP? We are comfortable with suppressing all logs because we have our own logging methods in place. I have tried in PHP setting error_reporting(0); which seemed to have no effect.
