Hi group, I would like to hook print driver for manage the file that the MS windows'user want to print. I have generate a virtual print driver which this command: "rundll32 printui.dll,PrintUIEntry /if /b "Virtual Printer Test" /f "%windir%\inf\ntprint.inf" /q /r "lpt1:" /m "driver" /z /u" but i don't know which dll or which program manage the file sends from the program ( M$Word, notepad, M$excel...) to the virtual printer. My component must be a printer, to be used with the print command in applications. Thanks a lot. Bye Riccardo. --- Questions?
