Any time I print a document, the printer prints one final extra page that only says PDF in the upper left corner.  It doesn't matter whether it is a PDF, a word document, or even the test page for the printer, it still prints this page that only says PDF. It has only started in the last few days, so I presume something has updated, but I'm not sure what would change to make the printer print this extra page.
