Printing functions

Hello! I have sent some questions about printing functions and unfortunately I had no answer. Does anyone here ever tryied to use them? I use IIS4-NT4 / PHP 4.06 and when I try to use those functions as said in the chapter LXVIII I allways receive a message saying that those functions are not available Can anyone say which one is my mistake? Thank you Deleo ------------------------------------- LXVIII. Printer functions These functions are only available under Windows 9.x, ME, NT4 and 2000. They have been added in PHP 4 (4.0.4).
