Since Gmail discontinued the "Fixed-width fonts" lab, here's a CSS hack to use a
monospace font for incoming mail:

1. Install the dotjs extension:

https://addons.mozilla.org/en-US/firefox/addon/dotjs/

2. Put this in ~/.css/mail.google.com.css:

/* Read messages in fixed-width font */

require 'barby/outputter/prawn_outputter'

Prawn::Document.generate("barcode.pdf") do |pdf|
  pdf.bounding_box([0, pdf.cursor], :width => 100, :height => 100) do
    Barby::QrCode.new("hello", :level => :h).annotate_pdf(pdf)
  end

Configuring problem-0.1.0.0...
Cabal-simple_mPHDZzAJ_1.24.0.0_ghc-8.0.1: Missing dependency on a foreign
library:
* Missing C library: zlib
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
