PDF page boxes and color issues

[kraft_it]

Hello,
I purchased Spire.Office 6.8.2 which contains Spire.PDF 7.8.9, and I encounter an issue when printing a PDF with an art box.
The size of our PDF is 8.25 x 3.25 inches and the size of our label is 8.125 x 2.25, when printing with Spire.PDF, it ignores all boxes (Trim box, crop box, bleed box, art box). Any suggestions how I can print just the art box?
Also, I am having an issue with the way spire prints colors, they don't come up they way I would like.
Attached you will find pictures of the issues I am having.

Printer: Epson TM-C7500G
Enviroment, Win10pro 64, English United States
Framework .NET 4.7.2

Here is the code I am using to print

Code: Select all

       
public static void PrintPDf(byte[] file, bool isColor)
        {
            PdfDocument pdfdocument = new PdfDocument();
            pdfdocument.LoadFromBytes(file);
            PrinterAccess.SetPrinterSettings(pdfdocument, isColor);
            pdfdocument.Print();
            pdfdocument.Dispose();
        }


settings

Code: Select all

 public static void SetPrinterSettings(PdfDocument pdfDocument, bool isColor)
        {
            var printerSettings = GetPrinterSettings();
            pdfDocument.PrintSettings.Copies = printerSettings.PrinterSettings.Copies;
            pdfDocument.PrintSettings.PaperSize = printerSettings.PageSettings.PaperSize;
            pdfDocument.PageSettings.Size = printerSettings.PageSettings.PrintableArea.Size;
            pdfDocument.PageSettings.Margins.All = 0;
            if (isColor)
            {
                pdfDocument.PrintSettings.Color = true;
                pdfDocument.ColorSpace = PdfColorSpace.CMYK;
                pdfDocument.PrintSettings.SelectSinglePageLayout(PdfSinglePageScalingMode.ActualSize, true);
            }
            else
            {
                pdfDocument.PrintSettings.SelectSinglePageLayout(PdfSinglePageScalingMode.FitSize, false);
            }
            pdfDocument.PrintSettings.PrintController = new StandardPrintController();
        }

Hello,

Thanks for your inquiry.
Sorry that we don’t have the same printer Epson TM-C7500G as yours, but when I tested with our printers, I did not find that all boxes were ignored like you mentioned. I noticed that in your code, when “isColor” is true, you set PdfSinglePageScalingMode to ActualSize. Please try changing it to FitSize and see if this problem occurs.. Also, please try to set the Paper Margins to 0, like the code below.

Code: Select all

            pdfDocument.PrintSettings.SetPaperMargins(0,0,0,0);

Besides, regarding the print color issue, I did notice that the colors printed by our Spire.PDF are inconsistent with the original file. I have logged it in our bug tracking system with the ticket SPIREPDF-4652. If there is any update, we will let you know. Sorry for the inconvenience caused.


Sincerely,

Thank you for answering,

I tried using you suggestions and I did not get the desired result.
Here is the code I used:

Code: Select all

       
public static void SetPrinterSettings(PdfDocument pdfDocument, bool isColor)
        {
            var printerSettings = GetPrinterSettings();
            pdfDocument.PrintSettings.Copies = printerSettings.PrinterSettings.Copies;
            pdfDocument.PrintSettings.PaperSize = printerSettings.PageSettings.PaperSize;
            pdfDocument.PageSettings.Size = printerSettings.PageSettings.PrintableArea.Size;
            pdfDocument.PrintSettings.SetPaperMargins(0,0,0,0);
            pdfDocument.PageSettings.Margins.All = 0;
            if (isColor)
            {
                pdfDocument.PrintSettings.Color = true;
                pdfDocument.ColorSpace = PdfColorSpace.CMYK;
                pdfDocument.PrintSettings.SelectSinglePageLayout(PdfSinglePageScalingMode.FitSize, true);
                pdfDocument.PrintSettings.PrintController = new StandardPrintController();
           
            }
                       
        }


Attached is the result.

As for the page boxes, I will ask again, Any suggestions how I can print just the art box?

Thank you.

Hello,

Thanks for your feedback.
Our Spire.PDF only supports printing the entire page of a PDF file. Sorry, we do not support printing just the art box in your PDF file.
If you have any other questions related to our products, please feel free to contact us.
