Be aware that the specific combination used of different versions of OS, printer, firmware and printing tool can affect results - as, unfortunately, bugs have sneaked in here and there.
My experience earlier using macOS Sierra 10.12.3, printer driver 16.10.1.0 and latest firmware at time of writing is here:
http://forum.luminous-landscape.com/index.php?topic=110646.msg959468#msg959468I tested ACPU, Canon Print Studio Pro 2.1.0 and ColorSync for printing targets with the Pro-1000. On this combination of hardware and software, I concluded that Print Studio Pro (PSP) did _not_ print targets as expected (unaltered), whereas ACPU and ColorSync were alike, and matching measurements included in Canon's own provided ICC profiles (should be a valid outside reference in my eyes).
So I (still) use ACPU or ColorSync, to my best technical ability shown to print targets correctly, and I achieve great accuracy on resulting profiles made afterwards. I use a somewhat less used toolset, ArgyllCMS, that works best for me regarding control and insight, like here (target testing in isolation), but that tool choice doesn't influence whether the printing tools print unaltered or not, just helps verify it for me). Use what profiling toolset works for you, but just ensure you trust what it does.
Some of my shown results were perhaps slightly misunderstood (might be unclearly explained), but not that important for conclusion. The tests only focused on determining which tool outputs unaltered target prints. I tested target print in itself to reference measurements by others, not results of final profile, several steps down the profiling chain (I think some thought that - but not relevant here for me, as target print should be trusted first, in isolation). I wanted here alone to clarify target print tool correctness itself.
PSP does work for some setups though (and actually fix what other tools seem to make bad), as Mark S has shown in his thorough articles - possibly with other combinations of software, or because some errors cancel each other out later on in the profile toolset chain. End-to-end pipeline is complex given the many mixes of software and usage. Once you find something that verifirably works on an absolute level on your specific combination, be happy and stick with it while it lasts. But finding that solution can, as shown on the forum, be a struggle and confusing sometimes... For me, my tests were pretty clear on my setup though. PSP was clearly shown _not_ to print targets unaltered.
So a heads up that it can take some investigation on your specific setup to feel secure you get trustworthy results, from start to end. Good luck, and fingers crossed these mishaps in software combos will get fewer and fewer.
