When we have used the internet on Princess we just went to the internet cafe, used our room card to sing in and just did what we needed. Once we had completed we logged off. We never had to print anything but did see people printing.
We were only charged for the time used and nothing more.

Fern, additionally the cost to print ONE page is $0.50. Kind of stiff.

Yes, you can do this. However, on the Caribbean Princess in May, I tried to print the boarding pass and Princess does not have (at that time anyway) Adobe on the machines, and this was needed to print my boarding pass.
