First, disconnect the printer, turn it off and unplug it from the power. Leave it that way throughout the following, until you are instructed to connect it up again by the installation software routine (or, at least, by that routine having completely ended and finished and exited etc.)
So: turn off, unplug, unplug your printer.
Go to your computer, to Control Panel - Devices and Printers, and remove all entries for your Samsung printer and its series, by clicking on each of its icons (or entries) and deleting.
Then go to Control Panel, Programs and Features, and use Uninstall (or Remove or Change/Remove) to get rid of all programs specific to your Samsung printer.
Then, reboot your computer: shut it down and start it up again.
Then, go to
and click on the Download rectangle for
Universal Print Driver 3 XPS (Driver) [etc.]
and wait for the download to complete and Save To file on your hard disk. Then locate the downloaded installer file, double-click on it to start the install routine, and install the drivers etc.
That should do it. If there is any problem at any point, feel free to stop short and Reply to me and I'll try to help you through the difficulty.
