Well, . . .
First, a disclaimer. I've used the products mentioned below, but not in your specific application. Caveat emptor.
If you're in the mood to experiment, you might get hold of a can of pastel fixative at your local art supply store. This is an acrylate, related to hair spray. [In fact, for a really quick test, just use hair spray. It's got all sorts of additives which may discolor with time, though.] When sprayed on a pastel drawing, it forms a protective film and holds the pigments in place. Pastels are nothing but pigment in a soft chalky base.
Try it on a simple ink-jet print on standard photo paper or, say, Hammermill OfficeOne 32# stock [An interesting low-cost alternative to ink-jet photo paper.] You might need more than one coat before the ink will withstand the waxing process with its wipe-on application and polishing.
If you are using a paste wax, sprinkle cornstarch on your cloth prior to polishing. Speeds up the process something fierce. It's also a bit messy. Cornstarch works well with old-fashioned paste car waxes when polishing your car, too.
