On MacOS, you can drop a PDF directly onto the window of a Printer's print queue, and it will be sent to print immediately (with the printer's default settings).
I'm looking for a way to do a similar thing with a specified folder. E.g. Any PDF or PostScript file dropped onto that folder (or saved there through any other method) will be sent straight to the printer.
The obvious thing is to use Folder Actions and an AppleScript, but I'm wondering if there's a neater solution that I've overlooked? Essentially, I'm looking for a filepath that works as a print queue.
