In Windows XP, I can use the following to install my printer INF file inside a .bat file automatically without user intervention: rundll32 printui.dll,PrintUIEntry /ia /m "My printer" /f .\install.inf /r "c:\temp\myportfile.dat" rundll32 printui.dll,PrintUIEntry /if /b "My printer" /f .\install.inf /r "c:\temp\myportfile.dat" /m "My printer" However, under Windows 7 I can't get it to work. Yes I ran it with administrator privileges. The INF file installs fine with the Add a printer manually so I know it works. The printer port is added correctly and appears as an option in the manual Add a printer. Any idea what is wrong? Any work around? Anyone free to accept a paid freelance mini job to do the installer? Thanks. --- Questions? First check the UndocPrint pages at http://www.undocprint.org/winspool To unsubscribe, visit the List Server page at //www.freelists.org/list/winprndev
