If you don't have a smartphone and still print your e-tickets for a train company like the french SNCF, you might want to only print what's necessary for the control team and yourself: your schedule and the QR Code.
Here's a way to only keep the top part of each A4 page (the smart ones will realize this gives multiple baby A5 pages), and assemble them in A4 pages again.
In a general case, you've split the number of A4 pages by two and have thus killed half less kittens (your mileage may vary).
