1320C ERROR MESSAGE: MISSING FILE: dlhsnziu.dll

I am installing a Dell 1320C printer with the latest drivers and everything is going fine with the installation on the reboot. Then a few moments later an error message pops up stating, "The file dlhsnziu.dll on the Dell Printer Driver CD-ROM is needed."  I insert the CD and and the missing file dlhsnziu.dll is NOT on the disc.  I then point it to the various printer driver downloads that I just installed and there is not any files there also.  There is one file on the driver disc that matches except for the extension: (dlhsnziu.dl_) it's a .dl_ and NOT a .dll extension!  Now I search all of my computer for the correct file (the one with .dl_ extension doesn't work) and get still nothing.

Any ideas on what next to do?  Maybe a clean reinstall of the printer? 

Many thanks for your help.
