Some of my cells in Calc have a background color which shows up on the screen but does not print out on paper. I am using Windows 11 with an Epson ET-2720 printer. I know I am doing something stupid, but I can’t figure out what I am doing wrong and it is driving me crazy, I updated LibreOffice to the newest version and Epson tells me its printer drivers are up to date. I would appreciate any suggestions but please keep it simple and detailed as I am eighty-one years old. Thanks in advance.
