Somewhere along the way, I found a reference to http://localhost:631/ & tried it.
Followed an uneasy feeling of not knowing where I was...
I thought localhost was my computer somehow (sorry to be so dumb).
But here I seem to be out in the internet somewhere...
But somewhere where they have a list of all my printers & where I (they?) can add/remove/change all my printer settings!
It all seems to be compatible with what I find under Ubuntu > System > Administration > Printers.
Changes made in one show up in the other OK, so no obvious conflict.
I now notice that the window for Administration > Printers is headed "Printer configuration - localhost"...
Can somebody please explain what is going on here (in simple language if possible)?
Should I be using localhost:631 or not?
Is it better or worse than Administration > Printers ?
Advantages & disadvantages?
