[leowgeo]

Hello
Basically i've got very strange issue with this printer
I'll go and explain it all
I've got 4 computers hooked up on network Os win7 home I've got Same MSHOME workgroup
The Canon ix4000 is connected to one of them I've shared it on the LAN and on security tab I've given the permission to EVERYONE allow to print
When i submit the print job from any network computer The computer printer is connected to looses the net connection
I've assumed it was the issue of net card on that comp i ve hooked up the printer on another comp did the exactly the same thing

Any suggestions wd b appreciated
