Print/autoprint Prawn-generated PDFs from Adobe Reader.

Prawn Print

Ruby gem that adds print and autoprint methods for Adobe Reader to generated Prawn PDF documents.

The documents can be opened in any PDF reader, but only Adobe Reader supports triggering printing in this way.

Installation

With Bundler for e.g. Ruby on Rails, add this to your Gemfile:

gem 'prawn-print', :git => 'git://github.com/barsoom/prawn-print.git'

and run

bundle

to install it.

Usage

# Open print dialog, but don't autoprint.
pdf = Prawn::Document.new
pdf.text "I installed Adobe Reader and all I got was this lousy printout."
pdf.print

# Autoprint it on the default printer, when opened.
pdf = Prawn::Document.new
pdf.text "Help! I am trapped in a PDF factory!"
pdf.autoprint

# Autoprint it on a printer where the name includes "LaserJet".
pdf = Prawn::Document.new
pdf.text "Help! I am trapped in a PDF factory!"
pdf.autoprint "LaserJet"

You can call print/autoprint at any place of the generated PDF – it doesn't have to be at the end.

Caveats

Sadly, autoprinting isn't fully hands-off – for security reasons, Reader will show a confirmation dialog.
