I'm currently developing a printing application and I'd like to print at high quality/resolution and I couldn't figure out how. I iterated printDocument.PrinterSettings.PrinterResolutions and got this results:
Kind - Resolution.X - Resolution.Y
High - -4 - -1
Medium - -3 - -1
Low - -2 - -1
Draft - -1 - -1
Is it possible to print at a specific DPI, like 300?
