Adobe PDF printer

I’ve been using Adobe PDF 9.0 printer to create Postscript files in Quark XPress for some time without issue. I have just got a new iMac and am transferring my files over. For some reason my new iMac cannot see the Adobe PDF 9.0 printer icon in the Printer settings pane. Without this Quark reverts to a Generic printer driver which means you cannot enter specific settings. I am running Sierra on both the old and new machine so cannot see what has changed! Any ideas? Thanks.
