ImageClass MF4350d Can't Print Single-sided MacOS Catalina

[robsmarg]

I recently switched over from Windows to an iMac running Catalina MacOS 10.15.6.  I had no problem installing the drivers.  My only issue is that I want to make one-sided printing the default on all my programs/apps.  I don't want to have to go into Settings every time I go to print something and change it.  How do I do that?

To fix this go to something you want to print. Then when printing, choose a print style→ Tap the “layout" drop down→ select “Finishing” make sure print style is 1-sided printing.
Dont print yet. Then go above where it says “Presets” and select “save current settings as preset”
Save Preset name to “One Sided” and make sure it has all printers selected.
Then Save.
Then print the page.
Make sure in the future that you have the “one sided" preset selected if you want to print one sided.
