How to Delete Job History

This is a dell 5110cn printer but the problem does not seem to be specific to this printer or maybe it is.

To make sure there is no confusion about what i'm asking since I have seen this question posted before and it was not understood.

If you go to the printer, you can select to print a job history report. This will give you a listing of prior print jobs and lists confidential/proprietary information that we prefer  is not viewable by others when we sell this printer. I have been trying to figure out a way to delete this history but surprisingly have come up with nothing. I'm assuming there must be a way to do this but I can't figure it out. Here is what I have tried:

At the printer: going through all reset options on the printer, no luck.

Connecting to the printer from a webpage: again, don't see any options to delete the job history

Accessing the printer properties from win7, don't see anything.

I will eat my hat if there isn't a way to do this, please help Dell!
