In the multi-process case, we might need to query the system (and maybe the network) for a printer with a name matching the one we're looking for. In order to not spin an event loop at dangerous times (since searching for printers is either asynchronous, or requires an event loop), we defer searching for the printer until we've already finished reflowing and rendering the document to be printed.
