As far as I am aware, there is no simple Processing call to send a document to a printer. It is likely that you will need java code for this. Look in java docs for documentation on Printable (it’s in java.awt.print).

Another technique uses DocFlavor found in javax.print. On macos DocFlavor.INPUT_STREAM.PDF seems to work ok. Could use DocFlavor.INPUT_STREAM.GIF if you have some other operating system and .PDF doesn’t work.
