Why is the print quality of photos printed twice by the Xiaomi Portable Photo Printer 1S inconsistent?

The print quality can be affected by the storage or usage conditions of the photo paper and printer. For best results, the storage environment of the photo paper is 15℃~32℃, and the storage humidity should be 40% to 55% RH. The best printing temperature of the printer is 5℃~40℃ and the operating humidity is less than 70%.
If the storage or usage does not meet the conditions, it can lead to issues such as inconsistent print quality, paper jams, paper removal errors, or even incomplete prints.
