How do I print ZPL Labels from the Command Line on Mac/Unix?
It's much easier to automate printing of ZPL labels from the command line than through any UI. On Mac/Unix, you can print in just two steps:
Find your ZPL printer's name in the list of attached printers:
$ lpstat -p -d
Use that printer's name and your ZPL's filename:
$ lpr -P <PRINTER_NAME> -o raw <FILENAME.zpl>
Some printers require additional options, such as page size and margins. To get your printer's specific options, use:
$ lpoptions -p PRINTER_NAME -l.
The command might end up looking something like this depending on the options it lists:
$ lpr -P PRINTER_NAME -o media=Custom.4x6in -o page-left=0 -o page-right=0 -o page-top=0 -o page-bottom=0 FILENAME.png
