output log format

[Janet Norton <cjnorton () fmtc net>]

I am trying to use snort to capture a copy of all print job data sent to a network printer.

When I use:
snort -l c:\dir_name host 149.59.152.28 
I like the way there are seperate files for packet fragments, but I do not want all the packet detail just the contents 
of data.

So I tried:
snort -b -l c:\dir_name host 149.59.152.28
I can extract the printer data more easily from this format, but everything was just appended to snort.log file.

I would like to run snort continuosly to capture all printer packets, and like the idea of seperate files, so an 
alternate task can process data as packets are received.  Can you help me determine the correct syntax to format output 
files for packet data only?  Any suggestions would be appreciated.
