How Can I Create a Banner?

Hi, I'm running Photoshop6 and I'm new to Photoshop. I created a sign with a document size of 37 inches wide and 8.25 inches high.

I'd like to print this as a banner I haven't had good luck. I'm using hp deskjet 845c and I do see an option that prints a banner but I'm doing something wrong because it doesn't print the full 37 inches which I imagine is about three pages long.

Can anyone help me to print my sign on multiple pages that I can cut and paste togeather to make a banner of approximately 37 inches long?

Thanks
