I have an HP Officejet 4315 All-in-One printer. I've had it about a year and a half now. I noticed, ever since I've had this printer, everytime I print something out that's more than one page, whether it's from the internet or from my word program, but especially from the internet since that's where I usually print stuff out from, whenever I print more than one page, there will be two or three paragraphs missing between each page that's printed. Why is it doing this and how do I fix it?
