For several months my firefox (now 76) will not print webpages. It use to work perfectly. However, for the last 4 - 5 months I get the error "an error occurred while printing." I have "refreshed" firefox; done a restore point for Windows 10; reinstalled firefoxe; checked firefox safe mode; done the config:about and deleted print_printer to no avail; done the pres.js recommendations; and followed everything firefox has suggested over the last few months and nothing has fixed the printing error/issue. I use firefox and then have to use Opera to print my page. If I can't resolve, I'll be making Opera my default and I don't want to do that. Any other clues or suggestions?

I received one reply that suggested I do the above, which doesn't solve the problem. Any other suggestions would be appreciated. I need this to start working.
