Has anyone put thought into printing Skia output?  Like, maybe, a surface that outputs postscript, the way the pdf and svg surfaces do?

A coder could always print out raster bands and have Skia render raster data, but that tends to be intensive use of memory, bandwidth and time.

We use PDF for printing.

What platform?

Chrome uses Skia→PDF→Pdfium→printer on all platforms.

We looked at writing a PS backend for Skia to talk directly to printers. It's feasible, but we'd also have to write a PCL backend to talk to printers that don't support PS.

If I understand the situation:
  • On MacOS, you can print PDF directly.
  • On most Linux desktops, the CUPS system will do the necessary conversions from PDF.
  • On Windows, Chrome relies on Pdfium to convert to PDF→EPS.  This is less than optimal, and there are several unresolved issues with this process.  Windows (6.0+) accept XPS as print format. Therefore, we have the experimental SkXPS backend.

Thanks!  I will look into the SkXPS surface as well as the PDFium library.

We are using SkiaSharp -with XPS printing. The SkiaSharp XPS handling is already great but could use some improvements! We've reported also some issues to the Microsoft team regarding XPS / .NET 5 so might only be getting better!
