My print appears double why??

Is the printer driver the right one for your model. Check Start, Printers & Faxes and see if the printer listed is the same model number as yours.
 
Delete the printer from the Printer & Faxes list. Close Windows. Restart and reinstall the printer in Printers and Faxes (add printer). See if that clears it.

Failing that, see if you can connect the printer to another computer without this issue arising (persuade a friend with a laptop to bring it round, maybe).
