are your machines capable to ping the printers on the other subnet? From our
discussion I'm supposing they can't. If not, it has to be related to routing.
Can you show us the routing table on one of the machines and the ip
configuration of one of the printers?
And can you post a traceroute from one of the machines to a printer?

Jorge you have the patience of Job. I have converted the two subnets of my
server to be 192.168.1/24 and 192.168.0/24. So here is the server routing
table:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 192.168.1.2 255.255.255.0 UG 0 0 0 eth0
192.168.0.0 192.168.0.2 255.255.255.0 UG 0 0 0 wlan0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0

The two network cards have addresses 192.168.1.2 (eth0) and 192.168.0.2
(wlan0).
From a machine attached to wlan0 I can ping both cards, I can ping any
machine on wlan0, but I cannot ping anything attached to eth0. The failure
is symmetric: from a laptop attached to eth0 I can ping anything attached to
eth0, I can ping both network cards, but I cannot ping anything attached to
wlan0.

Here is the routing table from a laptop attached to eth0 (i.e. the subnet
where I want to put the printers):

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.2 0.0.0.0 UG 0 0 0 eth0

I am not sure what traceroutes I should report since I can't get any routes
to work!


Best regards, Henry
