Hi..when i ping one of printer, i
got this reply;

$ping star1

ICMP Host Unreachable from gateway 190.254.46.6
 for icmp from moon01.com.my (190.254.31.52) to 190.254.52.10
ICMP Host Unreachable from gateway 190.254.46.6
 for icmp from moon01.com.my (190.254.31.52) to
to 190.254.52.10
no answer from starprn

 i did the ping from 190.254.31.52,
 it seems that there is a network
 problem from 190.254.46.6 ---> starprn.

We need your network settings.

What is your subnet mask?
How are the two subnets connected (or is it a 255.255.0.0) netmask?

Can you ping the printer from within it's own subnet?

how does your route table looks like ? (netstat -r)

 $netstat -r

Routing Table: IPv4
  Destination           Gateway           Flags  Ref   Use   Interface
-------------------- -------------------- ----- ----- ------ ---------
190.254.31.32 moon01.com.my   U        1    605  hme0
224.0.0.0    moon01.com.my          U        1      0  hme0
default      190.254.31.33         UG       1   7422
localhost   localhost             UH      162535100  lo0  

  1) my PC subnet mask : 255.255.254.0
 

 HOW SUBNET MASK IS BEING USE HERE?

base on your subnet we can see that the two ip addresses belong to two different network segments.

Sending ip traffic one subnet to another requires a router (or bridge). Data send from within your 190.254.31.x subnet can be seen by any address in the range 190.254.30.1 upto 190.254.31.254.

Data sent to subnet 190.254.46.x will use the system 190.254.31.33 as gateway.

Does the ping to your printer work on the this system?
This systems (31.33) is this a router? or a system with two network cards?

(may be stupid question, can't you configure the printer within the same subnet as your systems? Does it need to be in a different subnet?)

You can route to the other net on your own system by faking it as a router.
Use  route add net 190.254.46.0 190.254.31.254 0

Put this command in the inetsvc startscript to make it a static route. You also need to do this on all the other system on this subnet.

The only problem is broadcasts and multicasts, these will not travel across subnets.

I assume you dont filter packets between networks but how did you solve the netmaskproblem ? Is there a router faking this route that maybe dont allow all kind of traffic ?

On the printserver, run
snoop "yourhostname" starprn
and see if the cancelrequest reaches the server.
At the same you can see if and what the response is.
