I tried your solution but it still prints blurry. Yes, it's increasing some level of quality, but not as much as print from the acrobat.
Currently, I am using Syncfusion.Blazor.SfPdfViewer version 26.2.8. I also tried the latest version, 27.1.48, but still facing the same issue.
Image1 is from the acrobat
Image2 is from the spfdviewer
