custom controls: printing

[Phil Race]

That example is not great as it picked the one node type that knows how 
to do
something special with printing and completely overlooks it.

The print(Node) method it provides can print any node type but it is scaling
it to fit on a single side of paper. That's not ideal for a huge 
spreadsheet/table
as you won't be able to read the output without a microscope.

I was pointing to the method on webengine that you mention last below
as the one you should use and the example does not use that anywhere.

To get  proper pagination you need to explicitly call the 
WebEngine.print(PrinterJob) method
