Try to give this a shot: I solved it this problem updating the driver in the Print Server page on windows 10:

in the print server page > drivers, delete the old one, then click on "add new one" -> "Windows Update.." - wait a little bit, it's gonna take time before the tab opens - , search the manufacturer and the model of your printer (for me it was: "HP ENVY 5540 series") and then click on install drivers.  

(I have an HP ENVY 5540; it stopped working out of the blue and on the printers page it showed "Drivers unavailable"; I tried the metod shown above but it didn't work for me, I tried downloading the drivers from the Hp support page but it didn't work either).
