This sounds like a printer driver issue to me.
A true RIP would not be using a printer driver.
In reference to PSCS5 no longer having the No Color Management settings, which seemed to have been a knee-jerk response to improperly written printer drivers at the time PSCS5 was being written.
There are no profiles applied in the driver when printing B&W to Canon iPF printers so I don't see this as an OS problem.

This is making a mess of anyone using a B&W RIP with image space to printer space gamut transformations managed either via tone curves or a kTRC tag within an ICC profile (created by fantastic little utilities such as QTR Create ICC). Of course it also screws up the printing of step wedges for printer response evaluation/profiling (just like the colour world has been thrown a curve ball by the inability to print untagged targets and having to resort to special utilities to do such a basic task).
