press "start" on the bottom left of your computer a window opens
goto>"control panel" click on that
then> look for and click on "add/remove" programmes
then> look for the programme you want to remove then click on that programme's "remove" button
then> close the window ..(.red X in top right corner)
goto> start ( on the botton left of your screen) click on that and a window opens
look for the prompt that says "turn off computer" click on that
another window opens click on the "restart" button... this will turn off the computer and turn in on again (rebooting it)
check when computer is fully "booted up" that the programme has been removed.
with the printer turned on (I think)( to let the computer know that it is there )
install your printer software as prompt by the installation programme on your disc / or the wizard if you prefer and then reboot your computer as before. the drivers for your printer should be part of the package unless you need to update, then its off the the printer makers site.
check that your disc is clean no dust or light smears
I forgot to turn my printer on and it took an hour to realise it l.o.l.
