di-704p router question

i have now two routers off the dsl modem.
a beklin wireless the primary one and the di-704p router off that one.

all system can see the internet. no problem there.

when it comes to printing from the di-704p printer server.
the systems do not see the printer. get error everytime.
the software for the server is installed.

i tried changing the address from 192.168.0.1 to 192.168.2.1 then .2 but it
will not print.
i can see the di-704p web server as well as the beklin web server. were you
can make changes. not problem with that.
it is just printing that i can not get to work.

any ideas.
