HP Photosmart 7150 - Mac File Won't Print Properly On Windows 7 Networked Printer

I have an HP Photosmart 7150 networked on a Win7 PC. I followed the below directions to set up the share on my Mac with SnowLeopard. My issue is that a file that is, say 700 kilobytes gets transmitted to the spooler as several megabytes. As a result when I print a file it runs through all of the paper in the tray. If there is enough paper loaded it will eventually print the file. Somewhere in the middle it will print several pages of garbage.
