In fact I'm not sure on how to handle the sentence that "PDF context
has no colorspace". This is true because PDF contexts can embed for
example multiple images with each image having a different color
space.
As far as I remember for your problem, you're using that for your own
purpose (debugging) ? so you can find the colorspace associated to
your printer in the colorsync profile utility, with its path beside it
(or dig it from the device list like you said, but maybe manually
should be enough ?)
