Windows as LPD Server

Hello

I must use Windows as an Unix print server and therefore installed the
UNIX print services, which provide an LPD interface to the spooler.

When using the lpr command available from Windows, i am able to send 11
print jobs one after another. The next print job i want to submit takes 2
minutes 10 seconds.

I already goggled for solutions but only found a knowledge base entry for
NT4 and NT3.5.1 explaining, that the LPR/LPD command only uses 11 TCP
ports which (according to some specification) may not be reused for 4
minutes.

I faced the problem on Windows XP pro, and Windows Server 2003 std. I
assume, that all current versions are affected.

I need to submit as many small print jobs as fast as possible.

Does anyone know a solution or workarounds regarding this LPD limitation
in windows? Are there any registry keys which may be used to configure
timeouts and port ranges???

Thanks in advance
