HP8000N printing from Toshiba Portege 70

Among the numerous 7020CTs we have in a peer-to-peer network, we have one that’s been experience major printing problems to a HP8000N. I have checked everything from the NIC, cabling, apps, drivers, etc. but it continues to print erratically, page 1-5 then back to half of page 1 then 20 copies of pages 1-3…out of an 11 page document.
