How to install printer driver without printer connected.

[Joe Feely]

I have F12 installed from a live CD (on my AA1, I used an external DVD
rewriter).
I use a Dell 1720 laser printer 13 miles away (when I visit there), with
no IN connection.
How can I "install the required driver" while at home, from which I have
access to the IN (and the CD I installed from, though I've no handy
means of using this where the printer is).

I have tried Googling it.
Any pointers / guidance appreciated.

TIA
Joe
