What may not have been made clear, is that you can collect your ticket from any station with ticket-issuing facilities, regardless of what station you selected when buying the ticket. At one time, I think that you may have had to wait a bit longer before you could collect from a different station (I seem to recall EMT's website saying 15 mins from the selected station, or two hours to collect anywhere), but this doesn't seem to apply nowadays.
There are a number of stations where you can collect tickets that don't appear on the list. A station that I use fairly frequently is such a case: it has a booking office, but because it doesn't have any TVMs it doesn't appear on the list. I have been told by the booking staff to "just pick any station on the list".
