How to delete printer driver Windows 7

After upgrading to Windows 7 I reinstalled printer software and driver (HP Photosmart C4480) on both desktop and laptop. I have computers connected on Home Network but can only get desktop to print. Today I connected laptop directly to printer and still no printing. Tried reinstalling driver and software and still no go. After researching I suspect my old Vista printer driver is being used and not Windows 7 driver, apparently a common problem with HP printers. Having real problems finding out how to remove this.Bought up the MMC, went to file menu and selected add/remove snap in then I am supposed to scroll list and click on Print Management but its not in the list?? So went to start and typed in Print Management which appeared at top but when I click on it nothing comes up?? Can someone give me some advise on how to remove this old Vista driver?

 

Unfortunately this does not remove the driver.

 

No, printer device is not in Devices and Printers because I deleted it (by right clicking and remove device) at the beginning of this exercise and presumed it would delete the driver also. Then reloaded new W7 software/driver but could not get printer to work. Found a credible article stating that Vista driver could have been left behind therefore computer does not download W7 driver OR both drivers are on computer but printer still using Vista driver. Yes I am logging in as Admin and as stated in first post "Print Management" is not listed in MMC and when just typing in search it appears at top but upon clicking on it nothing comes up.:cry Will try your suggested Cleanup tools and report back...I did use CCleaner but will try yours
