Frequently a manufacturer will have a "series" of printers with "different" numbers on the model. It looks like in this case, Lexmark made the 640 series, and the 645 is just a "new and improved" version of the 640.
If the printer works well on this program, then this is the case. When you go online to register the product, more than likely the 640 program will auto load a patch to enable the extra feature of the 645 to the base of the 640. It is standard operations for many printer manufacturers.
Should this not be the case, then it would be advantageous to connect to the Lexmark website and get the current program specified for your printer.
This depends on which wireless printer you bought. What you need is a wirelss enabled computer and a wireless printer. A CD will come with the printer for software to be installed.

Have you installed a printer? Is the printer set as default?
A printer may be used by anyone. A personal computer is typically connected to the printer. The drivers for the printer must be installed on the computer. The user must give a print command.
You can find out what ink cartridges your dell printer uses by opening up the printer and checking to see what cartridges are already installed on the printer.
Check the obvious things first: Are you out of ink? Does printer need thorough cleaning or head realignment (there is software that was installed with the printer in your printer folder that does these tasks).
Check for paper jams. Instruct computer to cancel all print jobs then reset printer memory by unplugging printer from electric outlet, wait 10 seconds and plugging back in. If it still doesn't work, check the following: Make sure paper trays are installed correctly. Do you have sufficient ink/toner? Are ink/toner cartridges installed correctly? Is printer cable connected correctly? Is printer cable good? They can short out. Is the printer designed to work with your operating system? Is correct driver installed? Is the printer set as the default printer? Do you know printer is functional? Try connecting printer to another computer.
