> PDF's created with "[weasyprint|https://weasyprint.org/samples/]" appear to cause a massive spike in memory usage when printing. This can be seen in their "invoice sample" provided on their page (causes a ~2.5gb average spike for a 47kb file) or the attached test pdf (causes a ~1.8gb average spike for a 6kb file).
> Trying to source the cause in the java print libraries seems to indicate it's a problem with "nonsolid colors" being used in the drawing of the page (which we are passing off to a PDFPrintable). On my windows machine, normally a ({{sun}}) {{WPrinterJob}} gets created for printing, but for some reason these pdf's end up using a Paint flagged as incompatible which [fails the job creation|https://github.com/frohoff/jdk8u-dev-jdk/blob/master/src/windows/classes/sun/awt/windows/WPrinterJob.java#L793].
> Trying to print with just pdfbox from the command line gives similar results in memory usage spiking to what we are seeing in our application: {{java -jar pdfbox-app-2.0.13.jar PrintPDF -printerName PDFCreator test.pdf}}
