On my 2 year old 2017 iMac, I've been printing to my Epson SC P800 printer for almost 2 years with good results. I had used ColorMunki to calibrate the monitor in the past, but it went kaput on me. Before it did, I started getting a completely different print than what was on the monitor. Results were dull, with colors muted, not nearly as bright. So purchased a SpyderX Pro calibrator. Used the new software, no change in poor prints. Use the DisplayCAL + ArgussII (spelling?) software as many purchasers suggested, no change in poor prints. Called Apple support yesterday and went through over an hour with them, even having the internal iCalibrator thing, no change in poor prints. Apple took all data and is to get back to me in 3 days with any results. In the meantime, I'm looking to get opinions on why my printing results look drab, as compared to a nice image onscreen.
