Double-sided printing can reduce the use of paper and the production cost of paper, which is beneficial to environmental protection. In today's environment that consumes a lot of resources, it is our responsibility and obligation to reduce the waste of resources. Double-sided printing can reduce the thickness of paper and make it convenient for readers to carry and store. Many publishing organizations and periodicals require that the number of contributions should not be too large, so double-sided printing can reduce the number of pages, reduce the length of articles and reduce the burden on readers.

Now copiers and printers generally support automatic double-sided printing, which is convenient and fast. The whole process of double-sided printing can be completed with simple settings, which reduces the time cost of finishing. Therefore, from the perspective of environmental protection, paper length and reader's burden, double-sided printing is a better choice. Of course, in some special scenes, single-sided printing is also a necessary option.
