Lines are missing from the printouts

[jborbach]

When I print a PDF from Sumatra on my Epson WF3520, individual lines are missing from the printouts. At first, I suspected that some of the nozzles on my printer had dried out. However, when I open the PDF file in Acrobat Reader, it prints the documents without any errors. What could be causing this, and is there anything I can change in the Sumatra PDF settings to ensure the documents print correctly?

Not really a SumatraPDF issue as such all it does is "SHUNT" images into WPAI (WinPrint as Image)

That is an exceptionally high density printer (5,760 x 1,440 DPI)
The most common reason could be a buffer overflow or similar So the Driver has settings to mitigate high resolution etc.
If you can set the named driver to say 300 dpi ? it is less likely to fail on that basis as it will be 5% as many bytes.
