QuestionCreating a print event handler in a class, and calling it from my print dialog, I need human help on this Pin

This is my first time trying to to print directly to a printer using the PrintDialog and PrintDocument. I thought it would be like creating a PDF, where I just compose and create a file and print, but it looks like I'm forced to use an event handler to compose my print document using Drawing.

I was on the internet, and the examples where very simple and basic, but my document is going to be huge, and used many times in my c# winforms .Net Core 7 app. So I used ChatGPT to help me design a class, that I can call as my event handler, but I'm missing something in my class, or got it wrong on how all of this works.

On my Print Dialog Form, when I hit the print button, my code example ...
The printDefault.Question is what I'm trying to call, where Question is where I'm stumped ..
C#
if (result == DialogResult.OK)
{
    // Record the printer name used when the print job was accepted
    this.PrintObject.PrintSettings.DefaultPrinter = printDialog.PrinterSettings.PrinterName;

    if (this.PrintObject.PrintSettings.DefaultDocument != null)
    {
        var printDefault = new PrintDefault
        {
            Bol = this.PrintBol
        };

        // Subscribe to the PrintPage event of your custom PrintDocument.
        printDocument.PrintPage += new PrintPageEventHandler(printDefault.Question);

        // Start the printing process.
        printDocument.Print();

        this.PrintComplete = true;
    }
}

And my class ....
I figured that my class is an extension of PrintDocument, but I'm not sure. One of the dumb requirements is that I need the MongoDb collection document to generate the BOL form to print, because that has all my data I need to populate the document I'm trying to create. I'm not really sure if my design is sound or not, and may have to think of an alternative. But I feel like I'm really close, just missing something that I didn't think of.
C#
namespace SimpleBol.Classes.DirectPrint
{
    public class PrintDefault : PrintDocument
    {
        public BILLOFLADINGS Bol { get; set; } = null!;

        // Create a PrintPage event handler method
        public void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)
        {
            // Create the fonts we need to print with
            Font fontTitleBold = new Font("Arial", 16, FontStyle.Bold);
            Font fontTitleRegular = new Font("Arial", 16, FontStyle.Regular);
            Font fontLargeBold = new Font("Arial", 12, FontStyle.Bold);
            Font fontLargeRegular = new Font("Arial", 12, FontStyle.Regular);
            Font fontMedium = new Font("Arial", 10);
            Font fontSmall = new Font("Arial", 8);
            Font fontTiny = new Font("Arial", 6, FontStyle.Italic);

            // Create the brushes we need to draw with
            SolidBrush brush = new SolidBrush(System.Drawing.Color.Black);

            // Define the printable area.
            RectangleF printArea = e.PageSettings.PrintableArea;

            if (e.Graphics != null)
            {
                // Measure the size of the text.
                SizeF textSize = e.Graphics.MeasureString("BILL OF LADING", fontTitleBold);

                // Calculate the starting position to center the text.
                float x = printArea.Left + (printArea.Width - textSize.Width) / 2;
                float y = printArea.Top + (printArea.Height - textSize.Height) / 2;

                // Draw the text on the page.
                e.Graphics.DrawString("Date: ", fontMedium, brush, x, y);

                // Continue with your drawing logic for the rest of the document
                // You can access the 'Bol' property here if needed
                // For example, e.Graphics.DrawString(Bol.SomeProperty, fontMedium, brush, x, y);

                // For example, you can access the Bol property here:
                if (Bol != null)
                {
                    string date = Bol.BolDate.ToString("dd-MM-yyyy");
                    e.Graphics.DrawString("Date: " + date, fontMedium, brush, x, y);
                    e.Graphics.DrawString("Shipper: " + Bol.ShipperName, fontMedium, brush, x, y + 20);
                    e.Graphics.DrawString("Vendor: " + Bol.ShipFromVendor, fontMedium, brush, x, y + 40);

                    // Continue with more drawing logic as needed
                }

            }

        }

        // Override the OnPrintPage method to call your custom PrintPage event handler
        protected override void OnPrintPage(PrintPageEventArgs e)
        {
            base.OnPrintPage(e);
            PrintDocument_PrintPage(this, e);
        }
    }
}

On another note; since this is my first time, what's the best way to test during document composition. I threw out my cheap printer with cheap toner, and can't see having to print a sheet a paper on every test. Should I build a temp print preview first, and get it close enough there, and then use paper to fine tune?

Now I'm wondering if I should change my print dialog to show the preview first, and then hit the print button. The downside to being a rogue programmer is that I have no team to ask for help, and any help or opinions would be appreciated.
