If you are using Windows XP or 7, you could use System Restore to restore windows files from the day the problem started. Else look below.

I do not know what OS u are using. But if its Windows XP, you could right click the printer and uncheck User Printer Offline. And it should work.

To check if your printer is working Power off the printer. Now hold the paper feed button and power up. Then release the paper feed button. If the printer starts to print. Then the printer is ok.

To check if the cable is ok, start command prompt. Once u see the black screen type in this

DIR/W > PRN

If the cable and connection is ok, the printer should print a DOS screen capture.

If cannot, suggest u try the printer on another computer first to determine if the PC has something wrong.

Windows XP has the driver built in. Rarely corrupt unless u force overwrite the original files. Windows 7 also have the original files, but they are not preloaded. You need to run Windows Update from add printer to get it.
