DIN A4 dimensions in inches:

Width = 210 mm / 25.4 mm per inch = 8.27 inches

Height = 297 mm / 25.4 mm per inch = 11.69 inches

Resolution = (8.27 inches x 200 dpi) / 11.69 inches

Resolution = 1654

So, the image would need to have a resolution of approximately 1654 pixels wide by 2338 pixels high to maintain a printing quality of 200 dpi on a DIN A4 paper.

42.

Resolution = (8.27 inches x 300 dpi) / 11.69 inches

Resolution = 2338

for a printing quality of 300 dpi on a DIN A4 paper size, the image would need to have a resolution of approximately 2338 pixels wide by 3307 pixels high.
