The download is "From Setup to Printing" ensetupb.pdf 790 KB.
The page also offers "online user guides," but only for Mac and Linux.
The setup.pdf includes a brief section on "installing the software" but pretty much just says "insert the CD." It does not say what software gets installed. There is reference to "using the Solution Center" which may refer to the software you're missing.
Most drivers include all the functions that dedication "Solution" programs can use, so usually if you click on "Properties" when the Print window opens, you can use the "things Windows can do with this printer" to access about all the functions; but you may have to poke around a bit.
You can also double-click on the printer (Start|Settings|Printers and Faxes in recent Windows) or in Control Panel, double click the printer, Click on "Printer" at the top of the window that opens, look at properties.
With some printers, if you install their "programs" you're pretty much forced to use them, but if you don't install anything but the driver you may find that the Windows settings actually are more convenient for doing the same things. (I've learned to avoid letting the cheaper HP printers install their "helpfulshit."
Note that I've never looked at a Lexmark; so I'm guessing based mostly on Epson and HP experience.
