I have also seen the problem with Windows 2000 not zeroing the file size if you
don't check the 'LPR byte counting' check box. As far as my Sniffer(tm) and I
can tell it's a somewhat random number that appears, but usually quite large (in
the terrabytes).
The only solution I've come up with is to ALWAYS tell Win2K to count the bytes
so that the file size is explicitly given in the data header.

I am baffled by this one. I just looked at the W2K setup on the
sales droid's computer... First, you need to use the
Control Panel/Add Software/Windows Components/
Additional Network/Unix Printing
setup to install the RFC1179 support.
There were no options when I created a LPD port.
How do you find this option?
By the way, could you PLEASE double check to make sure that this
is the value that they are using? i.e. -
125899906843000
This 125,899,906,843,000 = 15 digit, not 12 digit number...
I thought it was actually 123,456,789,000 or something...
