"Remote Downlevel Document" on Net Printers

[Guest Groupex1]

I'm using Windows 2003 SP2 r2 for a print server hosting about 30 net printers.

Recently I noticed a document called "Remote Downlevel Document" in the

print queue ramdomly showing up on all printer queues, but it won't print

anything it just keeps showing up after a user prints to any of the networked

printers. I have search the net to find out what it is and I've found

everything from that is virus to printer connected locally on the print

server via LPT1. We have antivirus installed on the server and all XP

clients and none of them show any virus found, nor we have any of the net

printers locally connected to the print server. Could you guys help or point

to the right direction?
