Is there any way to change the default printing settings in the dialog box?
For instance, I would like the paper format to be always A4. Now it always appears as US letter by default and I have to change it each time.

You can use Cups administration page. You can access it by opening in your web browser.
Then select Administration -> Manage Printers
Select your printer and then, on the "Administration" dropbox choose "Set Default options". Change the default settings and finally press "Set default options". If it asks you the username/password use the same combination you use to login.
Via Ubuntu settings
On Ubuntu 20.04.1 LTS the settings can normally be set via
Settings --> Printers -->
But they don't always seem to take effect or perhaps there is another configuration conflicting which takes precedence.
