I am having some issue hopefully someone can help me out, I am not new to Mac but new to MAC with Active directory and printing.

We currently have three macs all running 10.7.2 all our printers are housed on a server 2008 printer server which works prefctly fine for windows.

I downloaded the Express driver from another thread on this fourm got it installed and I can use it to print no problem. Here is where the problem comes in.

To instal the printer (I might be doing this wrong) I go to sys pref, select printer, then I have to select windows find my printer server it shows my printers great select my printer then it was the driver which is easy enough thats all done now I can print but I cant seem to access any advance functions from any program such as duplex. staple all that fun stuff? am I missing somthing or doing osmthign wrong?
