I'm using the js sdk (page 13) and local desktop middleware (page 8) from https://www.zebra.com/content/dam/support-dam/en/documentation/unrestricted/guide/software/zebra-browser-print-user-guide-v1-3-2-en-us.pdf, I've noticed when I call zebraObject.send(zpl) it makes a http call to localhost on port 9100 at path /write. Can I send zpl commands to printers outside localnetwork through this sdk and middleware? how?
