Print only substack

[Charles Szasz]

I have main stack and I am using for the first time a print substack with one card. I found that when I call to either a card or print the stack I get a message that the card or stack has to be open. I tried open card and go stack commands which works but it shows the print card/print stack.  How can I print from a print stack without showing the card of the print stack?
