Type Alias PrintJobFn 

pub type PrintJobFn = Arc<dyn Fn(JobContext, Arc<[u8]>, u32) -> PrintJobFuture + Send + Sync>;

The print-job callback: given a job context, the document payload, and a copy count, returns a future resolving to the crate::raster::JobOutcome. The framework drives spooling/retry around it.
