Lexmark 9350 - Wireless and USB problem (tried both ways).

Print jobs do not complete on VISTA via OFFICE (WORD) 2007.
(If print out is more than 2 pages, this problem occurs. 1-2 page
document works fine.)

Detail:
job starts
lexmark display shows page 1 of 7 printing.
2 pages of 7 page prints
lexmark display screen then clears as if job finished.
One page (or 3rd in the series) is 'still' inside printer but blank.

If you try to send another print job to the printer, printer then
displays 'paper jam'.  Which is the 3rd page described above.

This seems to ONLY happen in OFFICE 2007 WORD.   If i print a multiple
page PDF, the job prints fine.

Note, if I print the same job on a 2003 Windows Server machine with
OFFICE 2003 (WORD), the print out completed correctly.

Although, I ran into a similar problem (on the 2003 Server) but the
job did not start (but was displayed on the Printer display), when
printing an OUTLOOK 2003 email.  NO pages printed.  There was no way
to fix the problem.  Job just would not print. Job had to be canceled
and printer turned off.  Printed job via HP deskjet, and job was
fine.

Any insight would be appreciated!
