I recommend that you use turbo mode when scanning/printing an image. Press Q and input a hex color code to change pen color. Press Space to scan your current drawing. Draw with left mouse button or tap on mobile. Press E and input your image code to print out the image. Decrease image print/scan quality with quality slider. (Higher value is faster but less quality) Remember to print images in the same quality that they were scanned in.
