The invention discloses a double-sided printing control method and device and a double-sided printer. The double-sided printing control method includes the steps that the length of printing data is calculated after the printing data are received; a first reference length and a second reference length are calculated; the printing data are divided into first data and second data, wherein the printing length of the first data corresponds to the first reference length, and the printing length of the second data corresponds to the second reference length; the first data are printed on a first side, and the second data are printed on a second side. By the adoption of the double-sided printing control method and device and the double-sided printer, the problem that in the correlation technique, paper is wasted when webs are used for double-sided printing is solved, and therefore the utilization rate of the second side of a medium can be increased, and the medium can be saved.

The invention relates to a pipeline compensator provided with a flow-guiding sleeve and a metal bellows which are both arranged along the horizontal direction. The rear end of the flow-guiding sleeve is provided with a ventilating ring gap communicated with the metal bellows. The pipeline compensator is characterized in that a sealing pipe structure arranged along the horizontal direction is positioned between the flow-guiding sleeve and the metal bellows, a seal cavity is formed between the metal bellows and the sealing pipe structure, the sealing pipe structure is provided with an extensible rubber bellows, the top side and the bottom side of the sealing pipe structure are respectively provided with check valves, the lower portion of each check valve is provided with a check valve opening, and the lower portions of all the check valves are tightly connected with the sealing pipe structure.
