V505 unable to share with other computers

I have viewed the various posts on this topic and I am still unable to share a this printer which is attached to a new dell computer.  I have three computers in a common workgroup - newwork ( all show up).   All computer can access the internet.

 The V505 is shown as shared but other computers cannot see it when I try to install  it  from these computers.   I have tried a reinstall of the dell v505 software but that does not help

Any suggestions would be greatly appreciated

Thanks

Bob
