"""A target model is matched without regard to case, as the scheduler does (Q-U8).

The scheduler finds printers for "x1c" among the X1Cs, but adding or editing a
queue job refused the same name ("No active printers for model: x1c"). The job
stores the printer's own spelling, so everything comparing it exactly agrees.
