Zebra Printing with CUPS no print ZPL or EPL

Question

I have a Zebra GK420d connect to OS X via CUPS. However, when I send files to it that are written in ZPL or EPL they are only printed in plain text.

Am I required to change to mode on the printer?

Answer 1

Contrary to what others said, you don't need to specially add a raw queue.

Instead, you can submit raw files into any queue using -o raw switch:

lpr -P CupsPrinterName -o raw path/to/label.zpl

Printer name can be found over that link in CUPS:

http://localhost:631/printers/

This also works on other platforms that use CUPS, like Linux.

Answer 2

You can create a raw CUPS queue with lpadmin. Here's the command line I used:

lpadmin -p Zebra -E -v usb://Zebra%20Technologies/ZTC%20LP%202824%20Plus?serial=XXXXXX -m raw

You can also set up a raw queue using the CUPS web admin at
