printer configuration

["Russell L. Harris" <rlharris hal-pc org>]

I am using Balsa 2.0.15 on the Gnome2 desktop in Debian 3.0.

I would like to be able to change the default print command string   
from "lp" to something such as "lpr -Phplj4ps".

But using:

   menu -> print -> printer tab -> "settings" and "location" fields

I discover that the "settings:configure" button is dimmed-out.  Under  
"location", I am able to select "custom" and then enter "lpr - 
Phplj4ps", but this change holds only for one print job; immediately  
afterward, the default reverts to "lp".

Am I taking the wrong approach, or has the ability to change the  
default print command string not yet been implemented?
