try this, download a program called "vuescan" choose to dl free version, when you installing it will ask you, "do you want me to install drivers which will work with just about with any hardware?" Say "yes" (Becarefull not to skip this step)
try a printing job or scanning (if you have scanner in your printer) within the program. If you manage it then close the program and try another print job, see if you can see printer name (it may show up with a weird name) -the screen before the job sent to printer. If that doesn`t work search for drivers in dell website but not your country of origin website (eg if you are in us look into uk website of dell) last option either wait for a driver which maybe forever or get a new printer.
