Mirage is €300!? At that price it should handle things well.
But I've never had presets failing or going missing with Aperture or Lightroom. And I'd rather not create separate, huge, TIFF files for printing.
Ultimately, I hope that PO will just add printer presets to CO. They have presets for many other things; it seems as if printing should follow along.
You don't have to keep the files. Just create 'em, print 'em, and toss 'em. The raw files will still have the same adjustments. Just keep a "print" variant.
Unfortunately C1 will not allow you to rename a variant so you will have to figure a workaround, such as a print color tag.
I wouldn't hold my breath on PO improving C1's printing capability. They seem to be more focused on color and rendering.
Another option is to keep Aperture or LR as your print engine and create a print catalog in either.
Although some don't like the CC subscription model, this is yet another reason to do it. You will find that C1 is not an all-in one like LR or (I'm guessing) Aperture.
Although its a great front end raw editor, its a bit lacking in some retouching areas, and you may find yourself needing to export an image into PS for final editing. So the CC is good way to keep that option open.
