The username is stored as a string in the "System" file;
I don't remember where.  The chosen printer is stored in "STR " 
-8192.
   I suppose you could set these, then delete the chooser; 
however I strongly recommend not doing this.  It is just
too useful for users to look in the chooser and see if the
printer is responding, and too many things can reset these
values.  You have to assume in a public setting that users
will add their own DAs and screw up your files constantly.
   Therefore, the cleanest solution I know is to make yourself
a modified chooser, install it, and hope it doesn't get replaced
too often by a user with his/her own Font/DA mover.  To modify:
get ResEdit, and a copy of the chooser in the Font/DA mover 
"suitcase" file.  Open this file with ResEdit, and edit the 
dialog box which contains the template for the chooser's main
dialog.  On my system (6.0.2) this is "DITL -16000" but your
mileage may vary;  it should look familiar when you see it.
Expand the dialog box & put the edit text field for username
out of the original rectangle;  then close back to normal 
dimensions.  Voila:  all the items are present bu the
user cannot edit the field.  (My thanks to Chuck Hutchins,
the Apple Education Coordinator here, for this idea).
