When I did that the first time there was and is still no drivers there?
There is no driver for the OS Version you selected. The driver may be included in your OS or you may not need a driver
I see now after actually clicking onto the driver link. Shady business practice to include OS's when there's no driver available.
However, if the printer won't self install according to the instructions that Al provided, there's still hope. If one uses Google Chrome, there's a Google Cloud Print option in Advanced settings which has worked successfully for myself numerous times.
Being that I have a lot of computers, most with dual boot or more OS's, Google Cloud Print is a godsend. All one needs is the Google Chrome browser & be signed into their GMail account, it's free & offers 15GB of Web storage (17GB counting Photos). All bookmarks, extensions & most other settings will work across most computers, to include Google Cloud Print. I'd imagine that if it works on Ubuntu 16.04 (base OS for Linux Mint 18), will also on 18.04, although I didn't have to follow all of the steps below, here's a guide if needed.
Of course, I never completed all of these steps, could be Linux Mint handles Google Cloud printing different than Ubuntu. The above was a random guide pulled from the Internet, and could be for older printers, as stated right under the bold print on top of page.
Thanks to CUPS and Google Cloud Print Connector, you can share your old printers using Google Cloud Print (GCP).
While I don't have an old printer to try this on, can say that Google Chrome Print works great with newer models, just try & see what happens. Either way, this is a viable option to use when native drivers cannot be found.
