Is there a way I can prohibit someone from printing or copying an excel
document that I send to them.

I have tried to protect the document and worksheet but you can still perform
these functions.

No internal protection will prohibit printing, though you can use an
event macro to do so. Of course, to bypass that, all the user would need
to do is disable macros.

If they can see it on screen they can print a screen shot.

If they have access to the file in the OS they can generally copy it.
