PDF file, 7 pages, 765 MB when printed?

I have a 7-page PDf file that I opened using Adobe Reader 8.1.2. On 1 particular PC, when this PDF is printed it begins to spool at something like 114 MB per page! This is when printing to a locally connected HP Laserjet 4050n using HP's PCL6 driver. When i print this PDF file from any other computer, all 7 pages are about 4.5 MB total and so it prints immediately. FYI I'm not using the "Print as image" option when printing in Reader. Help, anyone??
