I'm finding myself frequently printing plots, but as another poster below said, the font size is extremely small on things like patch and unit information. One way to counter this would be to print the exported PDFs at a larger setting, but this only gets one so far, because both the fonts and the artwork eventually start to get rather fuzzy. In the application itself, zooming into the paper view (or a plot) results in crisp, clean lines. Printing to a PDF? The nice vector-looking art and fonts look like they get turned into rasterized bitmapped messes.
I'm not certain if this is the way the "print to PDF" function in OSX works, or if this is an issue with how Capture is formatting the output. My guess is it's the latter, since I can export beautifully clean PDFs from other applications, and it's clear that the line art in those is a vector, not a bitmap. Being able to print really clean PDFs would be awesomesauce.
[edit] While we're on the topic of printing, the fixture report functionality results in very difficult to read reports straight from Capture. The margins are huge and there are no text settings, so lines wrap the whole way down the page, so it's necessary to export reports via the HTM function then scale down properly. But this is a very nitpicky issue, I suppose.
