You can have preferences that are dependant on environment variables. 
Try % help preferences.

Environment-specific preferences

    If you need to have preferences that are only active when a certain
    environment variable is set, you can use the following preference
    forms:

    ?E=environmentvariable=value:preference
    ?E!environmentvariable=value:preference

    Meaningful colons within these specifications can be quoted with the
    backslash character ("\").  For example, the following line would
    cause typescripts you start while the "DISPLAY" environment variable
    is "pgh:0" to be 600x600 pixels.

    ?E=DISPLAY=pgh\:0:typescript.geometry:600x600

You could have some preference lines like this:

?E=PRINTER=plum:*.formatcommander: <foo bar>

... where formatcommand would be <foo bar> when the environment variable
PRINTER is set to "plum."  Will this do the trick?
