how is it possible to use JSLink version loader for another Disp/EditForm. I want to have more DispForm for different print views – but the link to enter DFFS configuration is shown only at default DispForm.aspx/EditForm.aspx.
Sorry, but DFFS only supports the default form and not SPD created custom forms.
You can create different tabs for the print views. You can use rules to “route” the user to the correct tab – either by using a URL parameter and the trigger “URL Query string key equals” or by another rule.
