problem with certain pdf's

[Anonymous]

I am having difficulty printing certain pdf files on certain printers via cups.
When going through cups the printer(s) both new Kyocera and older HP models refuse to print and the queue gets hung.

And when I try to send the file directly to the printer's 9100 port using netcat (i.e. nc ) various things can happen:
1) On the older HP 4050TN the printer prints a bit of it and then hangs requiring cancel job and reboot.
2) On the newer Kyoceras part of the document will print but not all of it.

On one printer I get the error message:
--------------------------------------------------
ERROR: syntaxerror
OFFENDING COMMAND: --nostringval--

STACK:

-savelevel-
--------------------------------------------------
An example of the file is at

Can anyone help with this?
