I just released InvoicePrinter 2.0

InvoicePrinter is a Ruby library, server, and command-line client to make beautiful PDF invoices without browsers in no time. It's pure Ruby, but can be also used outside the Ruby world as a Docker container with a simple JSON API.

New features in 2.0:

New modern look & feel
More flexible buyer/seller boxes
Server is decoupled to a separate gem invoice_printer_server
New bundled fonts in a separate gem invoice_printer_fonts
Official Docker image
Prawn 2.2

Here is the project GitHub page, in the examples/ directory you can find a lot of code examples and how they look as PDFs. Follow docs/ to learn more about using it as a library, server or a command-line client.

Here is one example (download the final PDF):

And Ruby code to generate it:

#!/usr/bin/env ruby
# This is an example of a international invoice with Czech labels and English translation.

require 'invoice_printer'

labels = {
  name: 'Faktura',
  provider: 'Prodejce',
  purchaser: 'Kupující',
  tax_id: 'IČ',
  tax_id2: 'DIČ',
  payment: 'Forma úhrady',

# Default English labels as sublabels
sublabels = InvoicePrinter::PDFDocument::DEFAULT_LABELS
labels.merge!({ sublabels: sublabels })

first_item = InvoicePrinter::Document::Item.new(

  unit: 'hod',
