Here is a screenshot showing where the Epson Advanced Color Settings should be found. I'm pretty sure that Print-Tool is compatible with most if not all printers, though mine are all Epsons except for a Brother laser printer which actually does work with it. The dialogs available come from the specific printer driver you have chosen so be sure it is the correct one.
None of us have yet mentioned the specific macOS versions we are using, so that may be a source of unexpected behavior especially if you have performed an update since last using Print-Tool. I'm on a MacPro (trashcan) running Monterey 12.7.2. I had all sort of problems with Big Sur that caused me to set up an old iMac with Mojave just to be able to print at all. Monterey solved all those problems for me and has been completely stable. It is also the last macOS compatible with this computer short of using something like OpenCore Legacy Patcher to fix compatibility with Ventura or Sonoma which I have not done. (I have used OCLP to run Monterey successfully on a 2011 MBP.)
If you have done an update or upgrade recently, I would suggest reinstalling the printer driver first followed by reinstalling Print-Tool. Maybe do this even if you haven't made any system changes. The current version of Print-Tool is 2.3.4. I think Sandy has a typo in his post.
If you have a Mac with an Apple processor I have no idea if my suggestions will help.
