The first is the issue of paper compatibility. Generally, inkjet printers can be compatible with many types of paper, including but not limited to: printing paper, envelopes, photo paper, CD cover paper, etc. You can use anything you want, even high-end ones. All of them can be printed directly on some physical objects. However, because the consumables of laser printers are mainly toner, they are basically only suitable for ordinary paper, because if you change to special paper (photo) with low surface friction and adhesion, the toner may not hang, and it may fall off. Relatively narrow. The second is the issue of clarity. Inkjet printers are much stronger than laser printers.

Sunglasses can generally be divided into three categories: sun-shading mirrors, light-colored sunglasses and special-purpose sunglasses. The so-called sun-shading mirror, as the name suggests, is used for shading. People usually adjust the luminous flux by adjusting the size of their pupils in the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, many people use sun-shading glasses to block the sun to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. Light-colored sunglasses are not as good as sun-shielding mirrors, but they are rich in colors, suitable for use with all kinds of clothing, and have a strong decorative effect.
