For most USB printers, all you have to do is update your software and then connect the printer to your Mac. macOS automatically detects the printer and downloads any necessary software. For other printers, you may have to complete a few steps to add the printer.
I have done the installation as explained above (with Samsung Driver) and I am quite sure that it worked. But since Friday (maybe there has been an update performed) I loose 1 or 2 inches of the top of my document, no matter which software does the print (LibreOffice or Word).
If this is not solvable, can you recommend a printer which has downloadable software compatible with Ubuntu? (I am on the verge of returning the laptop to Dell and exchanging it for a laptop with a Windows OS --WHICH I DO NOT WANT!! but may have to put up with....I know you guys aren't at fault for this; it seems that Dell (for the first time ever!) is not providing sufficient info when items are purchased and then the consumer gets stuck having to buy more hardware/software from them to make their products work properly) 2b1af7f3a8
