C# Bitmap how to make a picture better?

Question

.NET

You need to print a piece of wine-form.
Naturally, I used Bitmap for this purpose, but the picture turns out to be of poor quality, blurry or something.
And it’s better not to see the printed one at all.
Tried Bitmap.SetResolution(float x, float y), just reduces the image size. Tried to change PrinterSettings.DefaultPageSettings.PrinterResolution - generally zero sense.
I ask for your help

Answer 1

Apparently the picture is too small, so when printed it is scaled. Hence the loss of image quality.

Answer 2

Dig in the direction of the dpi of the form, honestly tried to find where I saw about it, but could not.
