hi
I cheated and the wiki uses cups1311 to save doing some root things.
I also do not have any other computers but suggest you look, as they are your current packages, to see if you can add a networked computer, while my wiki added a local printer.
Forgive me if you already understood this.
2) I have no way of testing, but you may be better off, removing cups1311 and going for "normal" cups and add a networked printer?
