I've got a WPF window with quite some info on it which is molded to be a set size, exactly 6 x 4 inches.

If I try to print it from a local PC, it works, it prints full page and everything is fine and dandy.

Problem is, we use some hand-supported terminals (Motorola Symbol) that are set to use a 240x320 resolution.

Whenever I try to print the visual using the terminal, I get a page that is only partly rendered, the rest of the printing is completely blank. It looks like Windows tries to fit the WPF window to said resolution when I call Show and then prints it.

The WPF for the window is

and the code I use to print it

var test = new PrintReport(NUMDOC, REF, TRANSP, NUM, DIR1, DIR2, DIR3, DIR4, DIR5, CODEMB, dt);

        var printDlg = new PrintDialog();

        test.Show();

        test.Close();

        var ip = UtilExpedicion.ImpresoraEtiquetas;

        foreach (var queue in new PrintServer().GetPrintQueues(new { EnumeratedPrintQueueTypes.Local, EnumeratedPrintQueueTypes.Connections }))

        {

            if (queue.QueuePort.Name.Contains(ip))

            {



                var ticket = queue.DefaultPrintTicket;

                ticket.PageMediaSize = new PageMediaSize(PageMediaSizeName.ISOA4);

                ticket.OutputQuality = OutputQuality.Photographic;

                queue.DefaultPrintTicket = ticket;

                queue.UserPrintTicket = ticket;

                printDlg.PrintQueue = queue;



                printDlg.PrintVisual(test, "");

            }

        }

I suppose it has to do with Windows basically not visually creating something it supposes it can't be shown in the set resolution. I've got the WindowStyle to None and ResizeMode set to NoResize as well as fixed Height and Width for the window.

In this case I am trying to use the visual because we already had it and it would save me some time not having to go through creating everything in Crystal Reports (Which I still can't be sure would work either)

Any help is greatly appreciated.

Later Edit: Adding everything in a ViewBox made everything way smaller, came out in a fourth of the size, but all the elements where in there. So, it's a resolution problem. Now I just have to simulate a higher resolution. F# me.

I would try rendertargetbitmap.

The code below saves a picture of a control to disk as a file.
Adapt it to return the rtb,
Then set the source of an in memory image control to that.
You might then have to measure and arrange the image to force it to the correct size.
But I think that ought to allow you to produce an image of whatever size you like with whatever resolution you like from a grid and it's contents.
I'll include it all so I don't miss some piece out.

        public void GeneratePng(Grid mapGrid, string pngURI)

        {

            double dpi = App.mvm.SelectedDPI;

            double scale = dpi / 96;

            Rect bounds = VisualTreeHelper.GetDescendantBounds(mapGrid);

            RenderTargetBitmap rt = new RenderTargetBitmap((int)(bounds.Width * scale),

                                                           (int)(bounds.Height * scale),

                                                            dpi,

                                                            dpi,

                                                            PixelFormats.Pbgra32);

            DrawingVisual dv = new DrawingVisual();

            using (DrawingContext ctx = dv.RenderOpen())

            {

                VisualBrush vb = new VisualBrush(mapGrid);

                ctx.DrawRectangle(vb, null, new Rect(new Point(), bounds.Size));

            }

            rt.Render(dv);

            PngBitmapEncoder png = new PngBitmapEncoder();

            png.Frames.Add(BitmapFrame.Create(rt));

            using (Stream streamPng = File.Create(pngURI))

            {

                png.Save(streamPng);

            }

        }

I think I adapted this from some piece of code I found online.
