CUPS Printing Problem

I have setup a CUPS server on centos 5.3.
I m able to add printers(lpd,network etc) and clients(linux and windows) to this server. I m also able to print MS word and text files to this server.

The problem is that when i submit a PDF file to print from windows xp client, it is not printing...
The error_log file shows:

E [18/Nov/2010:10:29:30 +0530] Missing printer-uri, job-uri, or ppd-name attribu
