Well Bob I use an outside printer mainly for multiple image prints on my 7900. My initial reasoning was LR kept wasting paper and losing settings.
After using Mirage, it made things so much easier.
Bear in mind I'm using a roll printer, and using a roll with LR or C1 is just a pain in the ass.
That being said, using paper of a known size looks to be super easy in C1. As far as quality goes, I couldn't say.
The best thing to do is waste a couple of sheets and make that determination.
