[edit: can someone verify - this is the case for me and I'm in the US]

You will need an archived installer for Sierra as Apple has replaced previous Sierra purchases in the App store with High Sierra and Sierra is no longer available from Apple there.


All that aside 10.12 and 10.13 are for the most part identical. If you are having issues with your printer in 10.13 you were not having in 10.12 see this article

if problems persist contact the manufacture of the device and they may be able to provide you with a solution.
