Yes, I've done it many a time.
Do print to full-page A4 though as obviously, this will help the barcode reader at the turnstile.
I base this on people on here previously saying they've done this, but would be good to have it confirmed!
Your phone is A4 size, wow
Oops! Didn't really read the OP did I I have done it on my phone too though, you may have to play around with the zoom a bit.
I have done this and it works fine. I find it easier to zoom in on the barcode in the email and take a screenshot, I then use the photo at the turnstyle.

Well this opens up a whole new world of opportunities (as well as another can of worms).......Exactly what I did.
