Ok, i've checked here and everything seems to be working ok, (although i printed on my HP CP 3525 but using your ppd from the link).

To check what is wrong:
please select output path in System Printers preferences to ram:output.ps

Load and Print SYS:Docs/ModeEdit.pdf

Send me the file from ram:output.ps

You can also check how it looks like in Ghostscript
MOSSYS:Data/Printers/gs RAM:output.ps

escape and later enter key will move to the next page.
