Print at Home tickets on East Coast have a bar code clearly visible. The ticket barrier opens when the code is scanned and I have seen inspectors carry scanners too.
Could you carry show and scan a PDF on a smartphone or laptop in order to be accepted for travel or do you actually have to have a paper document? In principle the code can be scanned no matter which you use so I don't see why it could not be done.
