Comment (by pulkomandy):
Hi,
The issue is easy to see in the pcap. In both cases, we can see that the
printer TCP window reaches a size of 0 (meaning the buffer in the printer
is full and it cannot accept more packets). On the hrev51382 capture, the
computer sends a "zero window probe" after some delay, and does this until
the printer sends a "TCP window update" once it has enough space again in
its internal buffer. In the new capture, there is no zero window probe,
and when the printer sends a window update, the transfer does not resume,
and the TCP communication just stops there.
