Super simple PDF invoicing. InvoicePrinter is a server, command line program and pure Ruby library to generate PDF invoices in no time. You can use Ruby or JSON as the invoice representation to build the final PDF.

• Simple, no styling required, no calculation, no money formatting (bring your own)
• Pure Ruby, no dependency on system libraries or browsers
• Fast, so you can render invoices on the fly during requests
