$1000 for a luggage tag printer?
I think that is made for companies who want to give away luggage tags at trade shows as a way to advertise their businesses.
I am sure RCL has the facilities to print luggage tags if they want to do it - the point is that they don't want to do it anymore. They want YOU to do it, just like the airlines now want you to print out your board passes.
Its just another way to save money.
