Poor printing quality

[Ciruman]

We are trying to print a Javafx Node with a good resolution and we found out that the javafx prints with a poor resolution(in Mac and Windows). This is related to the following ticket:

https://bugs.openjdk.java.net/browse/JDK-8166194

We found a non-acceptable workarround in the Javafx code:

We added in J2DPrinterJob.printNode the following code: ((com.sun.javafx.geom.transform.Affine2D)ppg.getTransformNoClone()).scale(1.1, 1.1); And looks like this:

private void printNode(Node node, Graphics g, int w, int h) {
            PrismPrintGraphics ppg =
                    new PrismPrintGraphics((Graphics2D) g, w, h);
//++++++++++++START
((com.sun.javafx.geom.transform.Affine2D)ppg.getTransformNoClone()).scale(1.0001, 1.0001);
//++++++++++++END
            NGNode pgNode = node.impl_getPeer();
            boolean errored = false;

The difference is huge in the javafx controls.

Could someone help us about it?

Source code to reproduce the problem:

import javafx.application.Application;
import javafx.print.PrinterJob;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;

public class PrintTest extends Application {

    public static void print(final Node node) {
        PrinterJob job = PrinterJob.createPrinterJob();
        job.showPrintDialog(node.getScene().getWindow());
        boolean success = job.printPage(node);
        if (success) {
            job.endJob();
        }
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        Button print = new Button("Print");
        HBox hBox = new HBox(print);
        print.setOnAction(event -> PrintTest.print(hBox));
        primaryStage.setScene(new Scene(hBox));
        primaryStage.show();
    }

}

Left side you see the printing from javafx (blurry edges) and on the right side you see the sharp printing with the workaround applied.

Of course instead of using: ((com.sun.javafx.geom.transform.Affine2D)ppg.getTransformNoClone()).scale(1.0001, 1.0001); could be used: ppg.scale(1.0001, 1.0001); But the thing is how is the best way to flag it as "durty" during the printing rendering. The screenshots @streifi added are from the same JavaFX application printed to two PDFs using Mac. In Windows the result should be the same(not tested).

Here it is the Issue: https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8223372

Does anybody know how could it be fixed? Any hints are welcome.
