Why do I get a Blank Page between each Content Page on my HP Network Printer?

This is a Driver issue. Get the latest driver for your system and make sure you are using the correct protocol/port to connect to the printer.

Make sure you choose the right driver for your printer. (PCL or PostScript)

If you are using postscript the following applies. In some cases printing elaborate postscript documents can also have this result when the printer needs more memory to properly render the document.

If your drivers are up-to-date try to disable DEP (Data Execution Prevention).
