DV Tape - Print to Tape

I have recently been engaged in debate with a close friend of mine over an issue that has arisen through a short informative film we are making as part of a school assignment.
The assignment has been shot on DV tape with fairly high-end consumer (if that's not a misnomer...) cameras.
We have agreed that no editing should be done without the colaberation of all involved present to contribute and so it was with some degree of dissappointment that I agreed to let this friend of mine do some of the "trained-monkey-style" editing.

The problem arrose because he is too lazy to bring his tiny external harddrive to my place with the edited video on it.
He proposes that he compresses to some degree (I dissapprove of this because I believe that as much quality should be preserved as possible if the original data is not THAT fantastic in the first place...) or that he print it back to the DV tape out final cut pro.

Needless to say his is a Mac machine and mine, running Premiere Pro... is a Windows OS system.
The argument is as to whether there is a loss of quality in this process of going from tape to computer, editing, printing back to tape and then capturing AGAIN! to my computer.

I have done a similar thing in the past and had a significant loss of quality.
