Print Back and White issue

[Prata]

Hi,

I'm trying to create a document with printer settings black and white by default, so when the user opens the document and press print button this may be printed in black and white.

Code: Select all

           
var documentPath = "C:\document.docx";

Spire.Doc.Document doc = new Spire.Doc.Document(documentPath);

doc.PrintDocument.PrinterSettings.DefaultPageSettings.Color = false;

MemoryStream stream = new MemoryStream();
doc.SaveToStream(stream, Spire.Doc.FileFormat.Docx);

// return stream.ToArray()


This code is inside a function, and returns a byte[] because i'm using this in server side on a apsx page, and this file is going to be sent to the client.

The problem is when the user opens the document and tries to print, the document is being printed with color.

Regards,
JP.

Hello,

Thanks for your post.
Please kindly note that the property (doc.PrintDocument.PrinterSettings.DefaultPageSettings.Color = false;) is a setting for printer but not for the Word document. After setting this property, there is no problem if sending document to the printer and printing directly. However, here you saved the document to a stream, actually this setting cannot be applied in the saved stream. Thus, the document was printed with color when printing the stream directly on the client. You need to set the property before printing on the client. Hope you can understand.

Hi,

Thank you for this reply.

As i can understand, this means that i cannot set (doc.PrintDocument.PrinterSettings.DefaultPageSettings.Color = false;) and then save to stream, but if i SaveToFile (in local folder) and then open the document and click in print button it doesnt work either.
What do you mean with

(...) there is no problem if sending document to the printer and printing directly (...)

, i need to call a method directly in code and send this document to printer queue?
The solution i want is to download the document from a webpage, and then open and click print button or somehow send it to printer queue from this webpage.

Regards,
JP.

Hello,

Sorry to make you confused. Firstly, whether you save the Word document to stream or to file, this setting can not be saved since it is for printer but not for the Word document. Secondly, "there is no problem if sending document to the printer and printing directly" that means this setting only takes effect if you print directly before saving the document. Finally, our Spire.Doc supports printing directly by doc.PrintDocument.Print();. And based on your solution, you could try the following code to download the document from a webpage, open and send it to printer for printing directly. If there is any question, just feel free to contact us.

Code: Select all

 using (WebClient webClient = new WebClient())
 { 
     //download file
     byte[] data = webClient.DownloadData("YourFilePath");
     using (MemoryStream mem = new MemoryStream(data))
     { 
         //open file
         Document doc = new Document();
         doc.LoadFromStream(mem, Spire.Doc.FileFormat.Docx);
         doc.PrintDocument.PrinterSettings.DefaultPageSettings.Color = false;
         //send file to default printer and print directly
         doc.PrintDocument.Print();
         doc.Close();
     }
 }
