Quick Print Templates - Date/Time and Signature; Edit

Quick Print Templates - Date/Time and Signature; Edit

1. Setting the default Quick Print template is not intuitive, but I found the article to do this. I've defaulted to a Quick Print template of my own making. 
2. I've set the "date and time" and "signature" toggles to "on", expecting them to print on every note. 
3. The quick print output does not have neither date and time, nor the signature in print outs. 

Question 1: how to get these to print automatically on all print outs? I don't want to type all that data every time, when it is such a repetitive and predictive task. 

Question 2: how to edit a quick print template? To this point, I've only been able to "delete" and create "new". There doesn't appear (readily) to have an "edit" option. 

Thank you in advance!
