I just don't understand all these statements saying that it's not a problem printing boarding cards and etc.
When I'm away from the UK on leisure purposes, I just don't want the interruption to my leisure time, the hassle, or the worry of finding some hopefully accommodating computer and printer owner, and probably then having to pay for the privilege.
On business, I have far more on my mind to remember, and generally don't have the time to divert to such facilities.
Irrespective of Ryanair boarding cards, I also often struggle to find reliable internet connections of any sort whilst travelling, never mind the combo of reliable connection and quality printer. If the latter is available, it is at an additional cost.
There is a simple cost-benefit decision on this. Some people will clearly put up with the inconvenience of Ryanair's requirements to save a few bob, but please don't lecture the rest of us.
