About Printing On The Web

Version: 29-Feb-2012
Author: Julian Viereck <jviereck (dot) dev (at) googlemail (dot) com>

About Printing On The Web

tl;dr: Printing on the web is very limited. There is CSS3 Paged Media "Last Call" spec, that improves things, but has not been adopted by browsers yet. How about creating a new "WebPrintAPI" that does not use the DOM but is more like a simple canvas API? Would such a simple API be helpful for your printing needs on the web, or is it just suitable for very special use cases like PDF.JS?

About this document

This document is intended to sum up the current state of printing using the open web platform. It should serve as a foundation for discussion on how to get proper printing support added to the PDF.JS project (adding printing support is tracked here).

Ready to Assemble Design Pattern

IKEA Furniture Design Pattern (Assembly Service Included)

Motivation:

In pdf.js we need to do as much processing as possible in the worker thread. The result of this work is then often used in the main thread to rebuild an object. There is currently no consistent way to do this.
