Have a look at the WpfPrintingSample for more infos.

Simple WpfPrintDocumentSource.

WpfPrintDocumentSource printSource = new()
{
    OnPaginatorRequired = (options, details) =>
    {
        return new FlowDocument()
        {
            Blocks =
            {
                new Paragraph(new Run("Hello, World!")),
                new Paragraph(new Run("Page 2")){
                    BreakPageBefore=true
                }
            }
        };
    }
};

Advanced usage with custom options

WpfPrintDocumentSource printSource = new()
{
    OnPaginatorRequired = (options, details) =>
    {
        return details.Options[DocIndexOption].Value switch
        {
            "0" => new FlowDocument()
            {
                Blocks =
                {
                    new Paragraph(new Run("Hello, World!")),
                    new Paragraph(new Run("Page 2")){
                        BreakPageBefore=true
                    }
                }
            },
            "1" => new FlowDocument()
            {
                Blocks =
