On the Pineco.de site they've posted a tutorial showing you how to use the Laravel framework to generate PDFs with content provided from the system. To accomplish the content-to-PDF conversion, they make use of the dompdf library.

PDF generation is a core feature when our app contains invoicing or services that require a downloadable version of an information schema. Like in many other situations, a simple solution would do it instead of a full-featured package. Let’s see how to render PDFs easily.

Once the package is pulled in via Composer they add in a custom configuration to handle some of the basic settings including the paths to the fonts, the paper size and what DPI to use to render the final product. With that in place the post starts in on creating the custom PDF service, extending the Dompdf class and adding in a bit more Laravel-specific functionality for the service. After explaining this code they move on to updating the container to include the service via a provider and show the creation of a simple PDF controller. This controller uses the service to generate PDF output from the data in their invoice object and stream the results directly back to the client.
