Makes it easy to write ZPL & ZPL2. This Gem translates your Ruby Code into ZPL. You can then send your ZPL to your printers. In the future, this Gem will be able to directly interact with your Zebra Printers.
This Gem now outputs your Gem as a PDF Document (Prawn is now a dependency), because wouldn't it be nice to be able to see what your labels look like before trying to print? You're welcome.
Add this line to your application's Gemfile:
gem 'easyzpl'
And then execute:
$ bundle
Or install it yourself as:
$ gem install easyzpl
