This experiment propose new Javascript API called printservice. Web extensions can use this API to provide functionality related to print process enhancements.

The printservice experiment is located on github https://github.com/edabg/web-ext-experiment-printservice/tree/master.

This experimental API provide functionality to customize print process with features like:

• headers/footers
• media format
• margins
• silent printing (without print dialog)
• range printing
• output format
• print to file
• print to different printers

In general all features supplied by nsIPrintSetting interface.

There is bugzilla issue which address this need also.

If this experiment is useful and can be uplifted and implemented in firefox will be good, because it is needed to successful port of XPCOM jsPrintSetup extension and prolong his life.
