had that before had to go to immigration with a landlord, she refused to pay a fine for missing tm30 or whatever it is, even thought it's landlords responsibility to do that. So I had to pay 1600 fine. Left the next month. Mind you that was a year ago.
Yeah they should be able to print it out from the system. That is if they're registered with immigration. Usually no problems in condos, landlords lending a house or 2 may not give a toss.
It happened to me with Air Asia flying from Macau to Chiang Mai, checkin staff would not understand the difference between VOA and visa exempt /which I was on/. Anyway I had my flight out of Thailand but not printed out, they wouldn't let me on the plane without it, managed to retrieve my flight info on my mobile but unnecessary stress. Chiang Mai immigration never asked me for ticket out, hi, smile, photo, stamp, off u go. 3 minutes
