Setting header size in PDFKit with Ruby on Rails?

I ended up adding this code

PDFKit.configure do |config|
  config.default_options = {
    :page_size     => 'Letter',
    :margin_top    => '3.6in',
    :margin_right  => '0.3in',
    :margin_bottom => '1.3in',
    :margin_left   => '0.3in'
  }
end

to /config/initializers/pdfkit.rb. Worked like charm after I restarted the server.

How to Specify Font-Size for PDF report Rails

The gem uses the tool wkhtmltopdf, and merely passes in options that that tool will accept. Since it's a HTML to PDF sort of tool, you should specify the font size using CSS.

Rails: How to print model's details to A4 PDF page?

Basically there is two options: (any PDF creation requires a gem - no default PDF creation for rails).

1. Create a pure PDF using Prawn, You have to do all the formatting using the Prawn API

2. Create a HTML version of your receipt and convert it to PDF, One of the better gems to do this is PDFkit. which uses a web-kit powered browser engine.

They both work good, For one page documents I usually use PDFkit to convert HTML and for larger documents that are going have lots of pages I use Prawn because it gives you a smaller file size and handles multiple pages better.

My suggestion would be to make a HTML receipt and display it on the screen and give the user an option to save a PDF version using PDFkit.

EDIT: windows install. (not tested - windows and I have parted company.)

Download the windows installer for wkhtmltopdf: win-wkhtmltopdf

now create an initializer file, e.g. config/intializers/pdfkit_config.rb

in pdfkit_config.rb set the absolute path to wkhtmltopdf on your local machine:

PDFKit.configure do |config|
  if RAILS_ENV == 'development'
    config.wkhtmltopdf = 'D:\path\to\your\wkhtmltopdf' #this bit i'm not sure about
  else
    config.wkhtmltopdf = "#{RAILS_ROOT}/lib/wkhtmltopdf"
  end
end

for your production ENV you can actually just have a copy of wkhtmltopdf in you repo, a unix version of course. (remember to chmod +x it before you git add it)

How to print tilde characters correctly with PDFKit?

Make sure you are setting the encoding on your HTML to UTF-8. It is probably trying to interpret it as US-ASCII
