Ummm.. Do you actually have a program called lpr.exe in that location? It's not usual on Windows. (I rather assume you do since you give the full path, but still...) IOW, what happens if you type: dir C:\windows\system32\lpr.exe at a command promopt? Also: are you on a 64-bit system? If so, c:\windows\system32 probably isn't where you think it is. cf, for example: https://mail.python.org/pipermail/python-win32/2012-March/012121.html TJG -- https://mail.python.org/mailman/listinfo/python-list
