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.

Philosophy

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

Please consider buying my book or my Rails starter kit so I can work more on Open Source.
