How can you get the Pixma Pro-100 printing dialog options from iMac via Photoshop Elements?

I have been using a Pro-100 Printer with PSE and a PC Windows computer with excellent results for about 2 years. I recently switched to an Apple iMac “High Sierra” version 10.13.2 and now find that the printing dialog options I see are extremely limited (I can’t specify printing paper type and most other options I am used to seeing with my Windows computer. I was using PSE 15, which I traded up to last year but found that it wouldn’t work with my advanced version of High Sierra, so last week I sprung for PSE 2018.  It works but with poor printing dialog options.  To check to see if PSE 2018 was the problem, I installed it on my Windows computer and found that it gave me the full printing dialog options.  So, it seems that PSE 2018 is working fine with my Pro-100 (and with a Windows computer) but that there is a problem when I use it via my iMac.  Can anyone suggest how I can get back the full printing dialog with the iMac? (the printer driver is the most recent: CUPS Printer Driver ver. 16.20.0.0)
