printer settings

[irichmond44]

I have a TR 4520 printer using wifi connection to I-mac with Catalina op system. A couple of weeks ago, I modified settings to print photos. I then restored them, but printer will not do 2 sided and prrint speed is very slow. How do I get function back?

Try selecting these settings in the printer driver.

Thank you for the tip. Unfortunately I have not been able to access the printer driver preferences on my I mac, so I have had to use printer machine settings. There seems to be a problem of driver software compatibility with my OS which is Catalina. The thing that frustrates me is that it was working well before I temporarily switched to photo print.

Sorry. I  missed the macOS reference in your original post.

Here are some hints:

You could try a reset;

or delete and reinstall the printer:
