Printing PDF with FreeSpire.PDF

[lemaao86]

Hi,

I am trying to print an existing pdf file with FreeSpire.PDF in c# .NET.

I follow the examples I can find and have the following code.

Code: Select all

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(pdfTemplate);
doc.PrintDocument.Print();

I get the following error.

Code: Select all

'PdfDocument' does not contain a definition for 'PrintDocument' and no accessible extension method 'PrintDocument' accepting a first argument of type 'PdfDocument' could be found (are you missing a using directive or an assembly reference?)

I assumed that printing documents is not part of the free version, but from what I can see in the documentation, it should be.

Any thoughts?

Thanks for your help.

Hello,

Thanks for your inquiry.
Did you install Free Spire.PDF from NuGet in your .NET Core app? Kindly note that for .NET Core Apps, if you install our Free Spire.PDF from NuGet, it will use the .NETStandard dlls by default. Sorry that our .NETStandard dlls do not support printing at present.

To solve this issue, I recommend you can download the FreeSpire.PDF v7.2.0 from our website, manually reference the .NETCore dlls and then install the following library in your .NET Core App.
netcoreapp2.0
System.Drawing.Common >= 4.5.0
System.Text.Encoding.CodePages >= 4.5.0

netcoreapp3.0
System.Drawing.Common >= 4.7.0
System.Text.Encoding.CodePages >= 4.7.0

Besides, the method “doc.PrintDocument.Print();” is obsoleted, please use the new method “doc.Print()” to print PDF files.
If there is any question, please feel free to write back.

Sincerely,
Brian

Hi Brian,

Is this the same with full Spire.PDF version? For both the Free and Paid for version v6.2 from NuGet appears to have the print API, but anything above does not

[Brian.Li]

Hello,

Thanks for your inquiry.

For the free version, starting from Free Spire.PDF v6.10.6, we have removed the .NETCore dlls from the NuGet package. Therefore, when using Spire.PDF v6.10.6 and later versions, you need to download our component from our website if you want to use the print function.

As for the paid version, we have removed the .NETCore dlls from the NuGet package starting from Spire.PDF v6.9.16. But you can install this Nuget package (Spire.PDF.NETCore) to directly use our .NETCore dlls.

If you have any other questions, please feel free to contact us.

Thanks.

I'm hoping to evaluate the full version, but I am awaiting a response from sales, they seems to be a lot slower than support!

Hello,

Thanks for your response.
Sorry that our sales team was not able to respond to you in time due to the time difference.

Thanks for your help.

Are there any API documents? I can find examples, but it would be handy to have the full API docs for development.

Perhaps I am misunderstanding what you meant in your previous post. I have the Spire.PDF NuGet 7.5 package and the Spire.PDF.NETCore 7.5 NuGet package

However

Code: Select all

                                   PdfDocument doc = new PdfDocument();
                                    doc.LoadFromFile(filePath);
                                    doc.PrintSettings.PrinterName = printerSettings.PrinterName;
                                    doc.Print();


Does not compile

Severity Code Description Project File Line Suppression State
Error CS1061 'PdfDocument' does not contain a definition for 'Print' and no accessible extension method 'Print' accepting a first argument of type 'PdfDocument' could be found (are you missing a using directive or an assembly reference?)
Error CS1061 'PdfDocument' does not contain a definition for 'PrintSettings' and no accessible extension method 'PrintSettings' accepting a first argument of type 'PdfDocument' could be found (are you missing a using directive or an assembly reference?)

What else could I be missing?

Hello,

Thanks for your feedback.
Please note that the Spire.PDF NuGet 7.5 package and the Spire.PDF.NETCore 7.5 package are not compatible. To use the PDF printing function, you only need to install the Spire.PDF.NETCore 7.5 NuGet package.

Please remove the Spire.PDF NuGet 7.5 package from your project and try it again. If there are any questions, just feel free to contact us.
