It calls "hp-info -i -dURI". If the output contains "plugin = 1" the 
plugin is needed. system-config-printer also checks for "plugin = 2" to 
offer the plugin if it has optional enhancements. It uses the 
"plugin-reason" to tell the user which enhancements the plugin supplies. 
And it neverv creates a queue for a printer requiring the plugin if the 
plugin is rejected by the user. So non-working queues are generally not 
set up.
