    Is there any way to force all images and text to use grayscale on a page? I
    have a 2-page pdf where the first page is colored and the second page is
    black. The colors on the second page are black according to the print window
    inspector, but running it through the printer forces the 4-color option to be
    used.

    Settings for texts and images:

    • Text colors are all black - setting colors as: 0, 0, 0, 100 (CMYK) - these are showing up black so this is working!
    • Images are grayscaled png's: not working, showing up colored.

    I've also tried saving the images as JPGS.

    Try to save images in PNG grayscale.

    Tried that and no luck. I had to save each file as an eps using the settings
    Illustrator 8 / Macintosh Black & White. Doing that made the pdf 100% black.

    Mmmm, PNG grayscale mode is supported natively, so I do not understand where
    your problem is.
    Additionally, instead of using EPS I suggest to use SVG format that is better
    supported.

    When I embedded the png's after grayscaling them, the backgrounds of the png's
    were no longer transparent. I double checked the png's to make sure they were
    indeed transparent and were grayscaled, and made sure the only change to the
    code made was the paths of of the images.

    I did use SVG and tried several save settings - SVG Profile 1 and SVG Profile
    1.1 but I couldn't get the SVG's to load in the PDF. The were showing up
    garbled. Could be I was using a wrong setting when saving to svg!

    Anyways - EPS with the settings above finally worked.
