Note that this also means it is impossible to use an HPLIP Fax queue 
remotely.  In fact, any "custom" graphical interface is likely to suffer 
from this problem.

It would probably be better if you can find a way to communicate with 
your backend using the normal channels, perhaps in a similar way to how 
passwords are collected by the CUPS backends.  That is, using state 
reasons in the backend, providing translations for them in the PPD, and 
accepting inputs from job options.
