Printing with wrong dimensions

[fabiopires]

Hello,

I'm using Spire.Pdf to print transaction receipts on roll paper but the printed result is stretched when compared to the PDF file opened on the computer.

Does anyone know what I'm doing wrong? I've also noticed that this works well on Windows 7 PC. I only detect this problem on Windows 10, with the same printer.

Here is the code that I'm using.

Code: Select all

PdfDocument doc = new PdfDocument();
                doc.LoadFromFile(pdfFileName);

                doc.CompressionLevel = PdfCompressionLevel.None;

                doc.PrinterName = szPrinter;
                doc.PrintFromPage = 1;
                doc.PrintToPage = 1;

                doc.PrintDocument.Print();

Thank you in advance.

Hello,

Thanks for your inquiry. I notice that you are using the PrintDocument Class which will be abandoned. Please update to the latest version(Spire.PDF Pack(Hot Fix) Version:3.9.584) and use doc.Print() instead. If the issue still exists after trying, please share us with your PDF file. You could remove the confidential information.

Code: Select all

PdfDocument doc = new PdfDocument();
                doc.LoadFromFile(pdfFileName);
                doc.CompressionLevel = PdfCompressionLevel.None;
                doc.PrinterName = szPrinter;
                doc.PrintFromPage = 1;
                doc.PrintToPage = 1;
                doc.Print();

Hello,

Thank you for your reply. I was able to solve this problem adding a PdfPrintPageScaling.ActualSize parameter and now it prints ok on Windows 10. Why this was working well on Windows 7 and not on Windows 10, I don't know...

I'm using the Spire PDF free DLLs. That hotfix will also work for the free version?

Thank you.
