Ezprint
=======

Ezprint is a drop in replacement for the princely plugin. It uses PDFKit
as the backend instead of princexml, possibly saving you millions of
dollars. I recommend using the Rack middleware component of PDFKit to
print PDFs in rails, but this plugin makes an easy transition from
prince->PDFKit for those using princely.

Installation
============

Version 1.0.0 deprecates support for Rails 2. For Rails 2.x support,
install an earlier version.

gem 'ezprint'
then run "bundle install"

Example
=======

The examples here are similar to princely, since the
plugin is basically a reworking of the princely source

class PDFExample < ApplicationController
  def show
    respond_to do |format|
      format.html
      format.pdf do
        render :pdf => "My Awesome PDF",
               :template => "controller/action.pdf.erb",
               :stylesheets => ["application","print"]
               :layout => "pdf"
      end
    end
  end

  # Alternatively, you can use make_and_send_pdf to
  # render out a PDF for the action without a
  # respond_to block.
  def pdf
    make_and_send_pdf("file_name")
  end
end

Render Defaults
===============

The defaults for the render options are as follows:

layout:      false
template:    the template for the current controller/action
stylesheets: none


Using another PDF processor
===========================

While ezprint has been designed with PDFKit in mind, other PDF processors
such as princexml can be used. A princexml processor is included and can be used
by setting Ezprint.processor = :prince in an initializer.

It's also easy to create your own processor:

module Ezprint
  module Processors
    class MyProcessor < Base
      def self.process(html_string, options = {})
        # Code to return a PDF string from an html string here.
      end
    end
  end
end

Possible Gotchas
================

If you're getting a "Broken Pipe" error when rendering PDF documents, you may need to
install the wkhtmltopdf-binary gem or put it in your Gemfile.
