system preferences not working properly dropped printers and cant add back

Thanks for the screenshot. Everything looks normal there. You are in the default Keychain Access program in macOS, and checking your email login password. What is Keychain Access on Mac? - Apple Support

Most likely, when you logged in the first time, there was an option already selected to save your email password in Keychain, which is why you are able to find it again there.

Thanks.

Hello Anniem055,

Thanks for asking the Apple Support Communities for help with your printing issues.

First, it may be best to reset your printing system. This will remove any old info and drivers: Reset the Mac printing system to solve a problem - Apple Support

Once completed, you will need to re-add your drivers per the help article here: Add a printer on Mac - Apple Support

If you still have issues, check the troubleshooting here: Solve printing problems on Mac - Apple Support

If you still can't print, you may need to contact the manufacturer to check if you need an update or different driver. Thanks.
