HP Printer Won't print borders and lines?

Question

I have an HP Deskjet 5850 and ever since I connected it to the Vista operating system, I am not able to print documents that have charts, gridlines, borders, etc. I am trying to print PDF files and in the print preview the borders and gridlines show. When I print it, the lines aren't there. Word and Excell documents print fine. Anybody know what the problem is and how to fix it?

Answer 1

Looks like a printer driver issue.
