Now cannot ping print server from second machine

[AG <computing.account@googlemail.com>]

Hello (again)

I don't know if this is related to the connectivity issues reported 
earlier, but now when trying to print from a second machine, I am unable to.

The set up is my machine runs the CUPS print server and is directly 
connected to a USB printer.  I used to be able to print from the second 
(client?) machine, but since this issue following a problem-riddled 
reboot this is no longer possible.

I have tried to ping the server machine (192.168.1.40) from the client 
machine (192.168.1.29) but cannot.  I have stopped all the firewalls 
(firestarter) on the *.*.*.40 machine and still no dice.  The machines 
are still connected via a hub and that hasn't changed since before I 
rebooted.

The client machine (*.*.*.29) can access the Internet via the same hub, 
but packets are being dropped when that machine tries to ping the 
server.  The server machine can now access the Net, and can ping the 
client machine.

Any thoughts on what I should check out for?

TIA
