Acrobat 7 doesn't quite "always apply" the working space when
printing. If a device space is in the same process color model as the
destination (by process color model, I mean CMYK, RGB, or Gray), it
is left as device, otherwise the working space is used as the source
profile for the transform.
If I read this correctly the following discontinuity occurs:
PDF Content = untagged CMYK, therefore CMYK Working Space is used for
on-screen display. When printing, even if a custom profile is selected
as the destination, CMYK numbers are sent to the device, not
converting from CMYK Working Space to custom printer profile. The
result is a discrepancy between display and print.
The screen is not CMYK, so there must be a transform from the untagged
CMYK to the monitor RGB.
If you check "Apply Output Preview Settings" in the advanced print
dialog, it goes from the simulation space to the printer space. The
simulation space is, by default, the working space (unless there's an
output intent, in which case that becomes the simulation space). You can
change the simulation space in the output preview dialog.
