Hi

I'm using EO.Pdf to programatically produce pdf from html, then print it..

Code: C#
SavePDF(PDFFilePath, TempFolderPath);
PdfDocument PDFDoc = new PdfDocument(PDFFilePath);

PrinterSettings settings = WebView.GetDefaultPrinterSettings();
// set the settings from a custom print dialog
settings.PrinterName = printDialog.SelectedPrinter;
settings.DefaultPageSettings.PaperSize = new PaperSize();
settings.DefaultPageSettings.PaperSize.RawKind = printDialog.SelectedPaperSize;
settings.DefaultPageSettings.Landscape = printDialog.SelectedPaperOrientation.IsLandscape;
settings.PrintToFile = true;

PDFDoc.Print(settings, null);


It works fine when i print from a normal printer or "XPS document writer", but when i choose "Microsoft Print to PDF" it gives the following crash:


Code: C#
Exception:
System.Exception: Can not print to PDF device. Please use EO.Pdf to render HTML page to PDF.

The error happened on Windows 10, EO.pdf version is 18.1.91.0

Thanks

Hi,

You can not print a PDF file to another PDF file. The purpose of the print feature is to print to a real printer.

Thanks!

Hi,

Some of our customers ask us to print in PDF with their printer as they do with any program on Windows 10. Could you consider "unlocking" this feature.

Thank you.

Wouldn't it be easier if you just give the PDF file directly to your customer instead of having to go through another printer device to get another PDF file? What's the purpose of trying to print a PDF file through a PDF printer in order to get another PDF file?

Hi,

For my part, I was talking about EO.WebBrowser in which you put the same restriction on the use of a virtual printer.

We can't create a PDF edition of all the screens in your app just because you lock a Windows 10 feature... some of our customers just want to save in pdf what they see on their screen but they can't.

Thanks

You will need a license for EO.Pdf to convert any web page to PDF. What we can do is to enable this feature on EO.WebBrowser if you also also have an EO.Pdf license. In your case, since you have been an EO.WebBrowser license for a long time, we can upgrade your EO.WebBrowser license to EO.Total just for the price difference (the current subscription expiration date will stay the same after the upgrade). Please let us know if this works for you.

Hi,

When we use ".PrintToFile = true" feature the directory path set in .PrintFileName is not used.

Code: Visual Basic.NET
Dim printToPDFSettings As Printing.PrinterSettings = New Printing.PrinterSettings() With {
                .PrintToFile = True,
                .PrinterName = "Microsoft Print to PDF",
                .PrintFileName = "D:\sandbox\test.pdf"
            }

            webView.Print(printToPDFSettings)


The Save As dialog is opening but not in the directory set in .PrintFileName

Thanks.

Hi,

I do not believe this is supported yet. We will look into the browser engine's code to see if we can add this in our 2019 release.

Thanks!

Ok thanks.

Hope you could add this because we've taken an EO.PDF licence only for that...

Not exactly the same topic, maybe, but I get the occasional users that print the WinForms WebBrowser's HTML page to PDF Creator - because that's what they do in all apps and PDF Creator is the selected corporate tool for that job - and it'll print the page resized to sometimes 1/4 of the page and sometimes 1/2 of the page and so on. It happens on their Windows 10 tablets only with our app. Everyday programs work fine with printing to PDF Creator. I think it might be related to their size of icons and text settings, where it's enlarged, I'm not sure. I've not had the pleasure of looking at any of the affected computers since the cases are few and far between and these guys are constantly out in the field. I've also not managed to reproduce it myself, but I've seen their results. There, we recommend them to use the built-in "Save as PDF"-function but it'd of course be fantastic to not get e-mails about the issue. Although understandable if impossible to reproduce something off of the sparse and random crumbs for clues I've gotten over the years. As mentioned, I failed myself at reproducing it, so I was getting ready to blame the tablets, but then remembered the print to PDF Creator works for all other apps.

Thanks for the information. As you might be able to imagine, there isn't much we can do without being able to reproduce it first. So if you have found a way to reproduce it please let us know, and if we stubble on something that may resolve this issue, we will reply here too.
