How to save printing options of a Merlin project?
Printing settings are usually saved in the project but you may also select to save them in a workspace to be able to switch from printing options to printing options.
To save a workspace, just call “Window” > “Save Workspace”
If you don’t want to save in the workspace  any other settings, you should expand the shown groups, disable all other options except of the “print options“.
Decide whether to save the workspace in the project and have it available just in the current project or for all Merlin projects.
To activate a saved workspace, call “Window > “Workspaces” > [your workspace]
