A3 paper has been printed on both sides. Why is the reverse word and the positive word reversed?

Mainly did not consider the binding direction of paper. Pay attention to the binding direction when printing. If the page setting is horizontal and the binding direction is the default long side of the system (two sides of a rectangular paper are long sides and the other two sides are short sides), the system thinks that the page should be turned from the long side, so it is reversed for the convenience of reading.

Just change the binding direction to the short side. On the contrary, if the page is set to vertical, the binding direction will be shorter, and vice versa, so it will be changed to long side, or the binding position can be automatically changed to upper side in printability.

Extended data:

Structurally, the double-sided printing units used by different models of printers are completely different. Some models of printers install the duplex printing unit at the bottom of the printer host, while others are installed inside the printer host. For users who print a lot, double-sided printing can reduce the paper cost by half without increasing any investment.

But also has no influence on the printing speed. Because all the processes are completed automatically, the directional errors that may occur when turning pages manually are basically eliminated, but the double-sided printing unit is expensive, so double-sided printing is mainly aimed at professional users with special purposes.
