Looks like most PDF editors are, let's say, not quite there yet. Use pdfimages (of xpdf) to extract all images. Check the watermark is a bitmap graphics. If so, there's probably only one copy in the PDF, which you could turn into all-transparent with a hex editor. Use pdftk or whatever to remove the encryption. It's just a PITA anyway. You may have to doctor some FOSS to do that. Use pdftops, hope it's easier to doctor in the postscript. Try loading it into OO with pdfimport (search OO extensions). Remove background image (OO supports no other watermarks), reassemble PDF from OO. Give feedback to the manufacturer of said second-hand device, featuring the word morons or some such prominently. Buy other device next time. Put up with the annoying printout, or use the non-dead-tree variety instead.
