How much does it cost to print a photo on A4 plain paper? 150, how much cheaper can it be?

50 cents for black and white is not expensive, and one for color 3 yuan. There are many black and white ones. If it's the same picture, 20 cents each. If the difference between each picture is more than 100, you can negotiate with them that the price will not be less than 30 cents. If the same picture is printed by a fast printer, 150 15 yuan will do. A dime depends on whether they have a fast printer.
