Hello,

Thanks for your inquiry and sorry for the late reply as weekend.
Sorry to tell you that our Spire.PDF doesn’t support setting the resolution directly to 150. But we support setting the resolution to these patterns: Draft, Low, Medium, High. Below is the corresponding code for your reference.
If you have any other questions, please feel free to contact us.

Code: Select all

            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("test.pdf");
            pdf.PrintSettings.PrinterResolutionKind = PdfPrinterResolutionKind.High;
            pdf.Print();

Sincerely,
Brian
