If a DOS program, or any other program that prints to a port instead of
starting a print job using the Windows Print Spooler directly, prints to a
port on which you have a printer is installed, it will be redirected to that
print queue. Since it has no name for the print job, just data to the port,
it calls it "Remote Downlevel Document".

A search of the KB for "Remote Downlevel Document" would have answered your
questions.

This explains what it is:

Print Jobs to Windows NT Servers Named "Remote Downlevel Doc."

This explains that it could be a virus:

Zero-Byte Remote Downlevel Documents Appear in Print Queue

If someone could be printing from a DOS program, or any other program that
prints to a port, then that is something to look into. If not, it could very
well be a virus.
