I recently upgraded to Big Sur from Catalina on my IMac. I have two 3880’s which have been really great. Of course they are both using Cone inks. My first concern was when my Epson Printer Utility4 would not load… I tried a small print after a good printer test and all jets were fine. The print was set for my regular conditions but came out totally magenta. Not good. I searched for fixes, including drivers. Long and short saw me calling Epson. There are no drivers, yet, for the 3880 and no timeline known. I am sure this could also be with other printers.
As a double check I connected my MacBookPro, using Catalina, and printed the same picture. All was good.
Before upgrading I suggest you check your driver availability.
